One Drop of Fingertip Blood: Detect Hidden Nutritional Risks for Children When getting health check-ups for children, many parents face a difficult choice: venous blood draws can be dis-tressing for children and upsetting for their parents, while a basic complete blood count may not reveal early-stage iron deficiency or vitamin D deficiency. By the time frequent illnesses or slower-than-expected growth become apparent, valuable opportunities for early intervention may already have been missed. Getein Biotech can make children's health check-ups different. International Consensus Ferritin and 25-OH-VD are two core indicators in pediatric nutritional assessment: Ferritin, an essential indicator of iron stores, is recommended by the WHO and pediatric guidelines in many countries for the early screening of iron-deficiency anemia. 25-OH-VD, a widely recognized indicator for assessing vitamin D status, is broadly used in areas including childhood rickets, immune function, and growth and development. European countries and the United States have incorporated these two indicators into routine pediatric preventive care and rapid capillary-blood screening systems for high-risk populations, supporting microsample blood testing in primary care and emergency departments. Understanding the Numbers How should you interpret your child's "nutrition report card"? Many parents look completely puzzled when they receive the health-examination report: What exactly do these numbers mean? Ferritin (SF) Reference Standards According to the 2023 Expert Consensus on the Prevention and Treatment of Iron Deficiency and Iron-Deficiency Anemia in Children:     25-OH-VD Reference Standards According to the 2025 Consensus on the Clinical Use of Vitamin D and Its Analogs:     With a single test, you can clearly understand your child’s true nutritional reserves. A child being full does not mean the child is eating well; the data tell the real story. The "Pain" of Taking a Child for a Health Examination How many parents have experienced a scene like this? You take your child for a health examination. The nurse picks up a venous blood-draw needle, and before the needle is even inserted, the child is already crying inconsolably. The parent holds the child's arm still while the nurse repeatedly searches for a vein; if the first attempt fails, a second is needed. The child cries until drenched in sweat, while the parent's eyes redden with distress… Even when the blood draw goes smoothly, you still have to wait most of the day, or even several days, to receive the results. Getein Capillary Blood Screening One Drop of Fingertip Blood, Two Key Tests With a single capillary blood sample, two key tests can be completed simultaneously: 25-Hydroxyvitamin D (25-0H-VD) — assesses bone development and immune function Ferritin (Fer) — evaluates iron stores and provides early warning of iron-deficiency anemia Five Key Advantages of Getein Capillary-Bloo...

TB (Tuberculosis): Know It, Test It, Stop It TB (Tuberculosis) has followed humanity for centuries, often beginning quietly with symptoms that are easy to overlook. In 2024, an estimated 10.7 million people developed TB and 1.23 million died from the disease. Yet around 2.4 million people were either not diagnosed or not officially reported. Closing this gap begins with earlier, faster, and more accessible testing.     When Should We Think About TB? TB is caused by bacteria from the Mycobacterium tuberculosis complex, often reported as MTB. It most commonly affects the lungs, but it can also involve other parts of the body. Common warning signs include: •A cough that does not go away, sometimes with blood •Chest pain, fever, or night sweats •Unexplained tiredness, loss of appetite, or weight loss     These symptoms do not always mean TB, but they deserve medical attention - especially after close contact with someone who has TB or when the immune system is weakened. Why Diagnosis Used to Take So Long For pulmonary TB, sputum is the most common sample and collection is usually non-invasive. For decades, testing relied mainly on microscopy and culture: •Smear microscopy is fast and affordable, but it can miss cases when few bacteria are present and cannot reliably distinguish MTB from other mycobacteria. •Culture is highly reliable and remains important for further testing, but results may take several weeks.     Molecular testing changed the picture. Instead of waiting for bacteria to grow, it looks directly for MTB genetic material. Depending on the assay and testing workflow, results can be available within hours - giving clinicians useful information much sooner. Molecular POCT: Bringing Answers Closer Molecular point-of-care testing (POCT) brings advanced detection closer to the patient. Compact systems can support testing in clinics, community facilities, regional laboratories, and other decentralized settings. • Faster answers - from 30 minutes to 1 hour, depending on the assay and workflow. Getein's Akso MTB Real-time PCR Kit delivers results in just 37 minutes • Greater sensitivity than smear microscopy, helping detect more MTB-positive samples • Less reliance on long-distance sample transport and centralized infrastructure • Earlier information to support timely clinical decisions and follow-up Faster Detection. Wider Access. Better-Informed Care Getein offers two molecular POCT analyzers, GN 7000 Akso PCR System and GN 7120 Akso PCR System, designed for different testing throughput needs. With a streamlined "samples in, results out"workflow, both systems deliver MTB results in as little as 37 minutes, helping bring molecular testing closer to the point of care.   Both analyzers feature two reaction chambers. The GN 7000 provides four testing channels, while the GN 7120 provides 12, offering flexible capacity for different testing settings.     ...

The Echo of Tuberculosis in Your Immune System: Understanding TB-IGRA I. A Disease That Has Never Faded Tuberculosis (TB) is one of the world‘s oldest and most persistent infectious diseases, causing over 10 million new cases and 1.3 million deaths annually. It primarily affects the lungs but can spread via the bloodstream to bones, kidneys, the brain, and lymph nodes. The greatest challenge: Infection ≠ disease. About a quarter of the global population carries Mycobacterium tuberculosis without symptoms and without being contagious — a state known as latent TB infection (LTBI). However, when immunity wanes — due to aging, diabetes, HIV, or immunosuppressive therapy — the dormant bacteria may reactivate, causing active TB.     Thus, modern TB control is not just about finding active cases, but identifying who carries the bacteria and is at future risk. To do this, we need a tool that detects the immune system's memory of TB, not the bacterium itself. That tool is TB-IGRA. II. What Is TB-IGRA? TB-IGRA (Tuberculosis Interferon-Gamma Release Assay) is a blood test that does not look for the bacteria itself, but instead asks your immune system whether it has ever encountered TB. During the test, a blood sample is stimulated with TB-specific antigens. If T-cells recognize these antigens, they release interferon-gamma (IFN-γ), which is then quantitatively measured. A result above the threshold is positive; below is negative.     Its key advantage over traditional skin tests (TST) is that the antigens used are absent from BCG and most non-tuberculous mycobacteria (NTM), making TB-IGRA more specific and reliable. Additionally, it requires only a single blood draw with no need for a second visit, avoiding false positives caused by BCG vaccination.     III. Priority Groups for TB-IGRA Detection TB-IGRA is primarily recommended for the following high-risk groups: ①Close contacts of active TB patients (especially household contacts); ②Patients about to start immunosuppressive therapy (e.g., TNF inhibitors); ③Organ or stem cell transplant candidates; ④HIV-positive individuals; ⑤Immigrants from high TB burden countries. IV. Clinical Value of TB-IGRA Key clinical applications of TB-IGRA include the following: Aiding in the diagnosis of active TB: When a patient has symptoms or imaging findings suggestive of TB, but sputum smear is negative, a positive IGRA result can support clinical suspicion. Guiding preventive therapy decisions: A positive result indicates infection, but it cannot distinguish between latent and active TB. The decision to start preventive therapy should be made by a physician based on age, immune status, and underlying conditions. Excluding infection: In immunocompetent individuals, a negative result essentially rules out TB infection, avoiding unnecessary testing and anxiety. Our Solution for TB-IGRA Detection    

Hypertension: A Silent Killer Deserving your Concern Hypertension is one of the most common chronic diseases worldwide and a major risk factor for coronary heart disease, myocardial infarction, stroke, renal insufficiency, and even death. According to statistics, the annual number of deaths from cardiovascular diseases globally is approximately 19.2 million, and the number of deaths attributable to hypertension is about 10.8 million. Risk range     Hypertension can be primary (90–95%, unknown cause) or secondary (5–10%, due to conditions like renal artery stenosis, primary aldosteronism, or Cushing's syndrome). A blood pressure monitor tells you whether blood pressure is elevated, but it cannot answer why it is high or what damage has been caused. Priority groups for hypertension check-up 1. Young hypertensive patients (<40 years old). 2. Resistant hypertension (poorly controlled despite multiple medications). 3. Hypertension combined with abnormalities such as hypokalemia. 4. Patients with suspected secondary hypertension. 5. Hypertensive patients with coexistent obstructive sleep apnea. What are hypertension biomarkers Renin, Angiotensin I, Angiotensin II, ALD, ACTH and Cortisol are hypertension biomarkers using to assist in the differential diagnosis of primary and secondary hypertension by measuring hormone or factor levels, thereby providing a basis for clinical diagnosis and treatment. They are involved in the following pathways: Renin‑Angiotensin‑Aldosterone System (RAAS) The RAAS is a central hormonal cascade that regulates blood pressure, fluid balance, and systemic vascular resistance. When renal perfusion pressure drops or sodium delivery to the distal tubule decreases, the juxtaglomerular cells release renin. Renin converts angiotensinogen to angiotensin I, which is then converted by ACE to angiotensin II – a potent vasoconstrictor that also stimulates the adrenal cortex to secrete aldosterone. Aldosterone promotes sodium and water reabsorption in the kidneys, increasing blood volume and thereby raising blood pressure.     Hypothalamic‑Pituitary‑Adrenal (HPA) System The HPA axis is the body's central stress response system. CRH will stimulate the pituitary to release adrenocorticotropic hormone (ACTH). ACTH, in turn, acts on the adrenal cortex to secrete cortisol – a glucocorticoid that modulates metabolism, immune function, and vascular tone. Chronic cortisol excess leads to sodium and water retention, increased vascular reactivity to catecholamines, and ultimately sustained hypertension.     Our solution to fight against hypertension Getein offers hypertension testing on our advanced chemiluminescence platforms. These tests are not only easy to operate, but also provide highly accurate results, combining high sensitivity and excellent specificity.

It also serves as an effective tool for post-treatment confirmation of Hp eradication, ensuring successful management of Hp-rel...

 TORCH Diagnostics Solutions   TORCH is an acronym for a group of infectious diseases that can cause severe complications during pregnancy, potentially leading to miscarriage, birth defects, or developmental issues in the fetus. The test detects specific antibodies (IgG and IgM) in the mother's blood to determine her immune status and identify recent or active infections that pose a risk to the fetus. It is a crucial prenatal tool for identifying infections that can harm the fetus, enabling informed clinical decisions.   Application Scenarios     Features of Getein TORCH Diagnostics Test Kits ²  Suitable for different types of analyzers ²  Simple operation, easy to use ²  Need only 10 μL sample ²  Long shelf life: 36 months   Getein TORCH Solutions: TORCH Markers   Detection Platforms     T：Toxoplasmosis     Toxoplasmosis is an infection with a parasite called Toxoplasma gondii. People often get the infection from eating undercooked meat. You can also get it from contact with cat feces. The parasite can pass to a baby during pregnancy. Most people infected with the parasite do not have symptoms. Some people get flu-like symptoms. Toxoplasmosis during pregnancy may cause miscarriage and birth defects.   R:  Rubella     Rubella is an acute respiratory infectious disease. Typically, infected individuals present with mild clinical symptoms, primarily including skin rash, low-grade fever, and localized lymphadenopathy. As the rubella virus is a teratogenic pathogen, infection in susceptible pregnant women—those without protective antibodies—during early pregnancy can lead to miscarriage, stillbirth, or the birth of a child with Congenital. It is recommended that all women who are planning a pregnancy or undergoing assisted reproductive technology be screened for RV-specific IgG and IgM antibodies.   C:  Cytomegalovirus     Cytomegalovirus is one of the most common pathogens responsible for congenital infections worldwide. The virus can persist latently in various bodily fluids such as blood, urine, and breast milk, and is transmitted through multiple routes. Individuals with compromised immune function are highly susceptible to CMV infection, such as those with HIV infection, organ transplant recipients, individuals undergoing pregnancy and childbirth, and those with malignant tumors.   H： Herpes simplex      Herpes simplex virus is a widespread viral infection that affects millions of people worldwide. It belongs to the Herpesviridae family and is classified into two main types: HSV-1, which is primarily associated with oral herpes, and HSV-2, which is more commonly linked to genital herpes. Many individuals infected with HSV are asymptomatic, serological testing can detect these carriers, differentiate between HSV types, and provide strong evidence for clinical diagnosis.   Ref...

All You Need to Know About Hormone Testing Hormones are the chemical messengers that play a pivotal role in regulating a wide range of physiological functions in the human body, from reproductive development and fertility to mood, metabolism, and bone health. When these hormones fall out of balance, they can trigger a cascade of health issues—from irregular menstrual cycles and infertility to low energy, mood swings, and even chronic conditions. Sex hormone testing is a powerful diagnostic tool that helps healthcare providers assess hormone levels, identify imbalances, and tailor personalized treatment plans. In this guide, we’ll break down the six key hormones included in a standard sex hormone panel, their roles, and what your test results might mean. The 6 Key Hormones in a Standard Panel Each hormone in the panel serves a unique purpose, and their interactions are critical to overall health. Below is a detailed breakdown of each one: 1. Follicle-Stimulating Hormone (FSH) Role: Produced by the pituitary gland, FSH is a cornerstone of reproductive health. In women, it stimulates the growth and maturation of follicles in the ovaries—each follicle contains an immature egg. As follicles develop, they release estrogen, which signals the pituitary to regulate FSH levels. In men, FSH promotes sperm production in the testes by supporting the function of Sertoli cells, which nourish developing sperm. 2. Luteinizing Hormone (LH) Role: Another pituitary hormone, LH works in tandem with FSH to regulate the reproductive cycle. In women, a surge in LH (known as the “LH surge”) triggers ovulation—releasing a mature egg from the ovary. After ovulation, LH stimulates the remaining follicle tissue to form the corpus luteum, which produces progesterone. In men, LH stimulates the Leydig cells in the testes to produce testosterone. 3. Estradiol (E2) Role: The primary female sex hormone, estradiol is a type of estrogen produced mainly by the ovaries (in women) and in small amounts by the adrenal glands and testes (in men). In women, it drives the development of female secondary sexual characteristics (e.g., breasts, hip width) during puberty, regulates the menstrual cycle, maintains uterine lining health, and supports bone density. In men, estradiol (converted from testosterone) helps regulate libido, bone health, and sperm production. 4. Progesterone (P) Role: Produced by the corpus luteum (after ovulation in women) and the adrenal glands (in both sexes), progesterone is often called the “pregnancy hormone.” In women, it prepares the uterine lining (endometrium) for implantation of a fertilized egg and maintains the pregnancy in its early stages. It also helps balance estrogen’s effects, supporting mood and sleep. In men, progesterone is a precursor to testosterone and helps regulate sperm maturation. 5. Testosterone (T) Role: The primary male sex hormone, testosterone is produced by th...
