Methods of detecting antibody antigen complexes are commonly referred to as immuno methods. By determining the amount of immune complexes formed after the reaction to calculate the concentration of the substance to be measured.

1. What is an immuno-bio chemical test for?

Tests are used on the basis of the body's immune system: To fight germs, foreign substances enter the body, the immune system produces antibodies. Antibodies are proteins that can be linked to a specific germ or substance, like the key that fits into a specific keyhole. Antibodies catch germs or foreign substances, neutralization them and attract other immune cells.

Immuno-tests are used in laboratories by creating precisely artificial antibodies that are suitable for substances or pathogens. When these antibodies come into contact with blood, urine, or stool samples, they are associated with the right substance or pathogen if found in the sample.

Immuno methods:

  • Immunity measures turbidity
  • Immunofluorescent immunity
  • Immunofluorescent electrolysm

Blood test

Immuno hygiene tests help identify pathogens

Share99 Times City International Health Hub currently uses all three methods.

The turbidity immunosymix test is used in the dosing of substances with not too small molecular weight such as: CRP, IgA, IgG, IgM, Microalbumine, Prealbumin …

The immunofluorescent test, which has now been practical, and the technology proves to be more accurate test results, a wide range of measurements, no need to dilute samples and is more sensitive than normal color-measuring ELISA, EIA, FEIA methods and does not require long incubation. Photofluorescent immunosmmunity tests are used to analyze many compounds of such importance as pharmaceuticals, hormones and other genital markers.

Immunosymed electrolysmization tests, using three types of principles: sandwich principle, competitive principle and bridge principle.

In particular, the principle of competition is used for the analysis of extremely small substances such as FT3, FT4, Cortisol, Testosterone, Estradiol, Progesterone

Sandwich principle: used for the analysis of larger substances such as: TSH, FSH, LH, PSA, AFP, CA 19-9, CA 15-3

The principle of bridge helps to detect antibodies in the sample such as IgG, IgM, IgA

The sandwich principle of photontheization immunofluorescent immunofluorescent techniques.

Immunosy tests are widely used, including:

  • Allergy tests: to detect antibodies against allergens such as pollen, flowers, grass or certain foods.

2. Immuno-biomedification tests at Share99

Currently, Share99 Times City Health Hub has been successfully performing a test of 36 anomalies, which can be found at the same time as common causes of diseases such as shrimp, beef, mold, house dust …

  • Detection of infectious germs: Patients with bacterial tonsillitis, ASLO tests allow the recognition and dosing of antibodies against streptolysin O in the patient's body. With the detection of this antibody helps to prove that the patient is or has ever had a sysential infection. In addition, the ASLO test is also useful to properly identify inflammation of the uphococcal, joint pain caused by group A sysentosis or other causes.
  • Diagnosis of heart attacks and thrombosis: Immediately after a heart attack or if someone has thrombosis, higher levels of a certain protein are found in the blood. Troponin T, with a half-life of about 2 hours, can be increased in the first 3-4 hours of plasma after an acute myocardial infarction and increases to 2 weeks, so it can be in place in case of diagnosis and monitoring of the development of acute coronary syndrome. CK – MB can be used more usefully than Troponin in monitoring for re-infarction or prolonged infarction because an increase in CK–MB levels lasts only 2–3 days after a myocardial infarction, while an increase in Troponin can last up to 14 days. Thus, if myocardial infarction recurs early, CK – MB has decreased immediately, and if the myocardial infarction lasts, after 3 days, the CK – MB activity is still high. CRPhs is not only a biological marker of inflammation, but also a factor that is directly involved in the process of atherosclerosis. CDC and AHA have recommended the following guidelines to assess future risk of cardiovascular disease: CRPhs < 1 mg/L: nguy cơ thấp, 1 – 3 mg/L: nguy cơ trung bình, > 3 mg/L: high risk.

  • Cancer screening tests: Using advanced immuno-testing techniques that can detect cancer markers. In gastrointestinal cancer: AFP increases in liver cancer, germ cell cancer. CEA increases in gastrointestinal cancers such as: cancer of the esophagus, liver, pancreas, colorectal, ovaries, uterus … CA 125 plays a role in the diagnosis of ovarian cancer, examining the success of the treatment process. Although SCC is not suitable for scab cell cancer screening because of their relatively low specificity and sensitivity, they are the optimal test to monitor the progress of the disease and can assess the therapeutic response of scab cell cancer when primary and recurrent. High CA 15 -3 is often used to monitor the therapeutic response and recurrence of breast cancer.
  • Urine test: If sugar, blood, protein or inflammatory cells are found in the urine, it may be a sign of diabetes, urinary tract infections or kidney damage.

  • Pregnancy in women: Beta HCG is performed to check the concentration of HCG present in the blood or in the urine. Helps diagnose pregnancy or not getting pregnant, used to find an extra-intra-uterus pregnancy, using this test in combination with other screening tests to find if the fetus has an increased risk of suffering from birth defects, such as Down syndrome.
  • Rapid testing of medications: The test detects hallucinations such as ecstasy, marijuana, cocaine, and certain drugs that cause neurological effects, including synthetic drugs, morphine, or sleeping pills.

Thereby, it can be seen that immuno-bio-testing is increasingly commonly applied in the medical field.
