What determines the rapid blood test?

Express blood test helps to quickly determine the blood group, as well as to identify various diseases in the patient. For example, using it, you can distinguish a bacterial infection from a viral infection in less than two hours. Express blood test is useful not only for treatment, but also in the fight against resistance to antibiotics. Earlier, in order to confirm the diagnosis of such diseases, it was necessary to wait about two days.

Express analysis is based on a process called chemiluminescence. Scientists have established that white blood cells, which fight against viruses and bacteria, have different chemiluminescent indicators. These indicators are easily detected in the blood in just a few hours. Since the symptoms of viral and bacterial infections are usually similar, doctors often prescribe antibiotics to patients with a viral infection. This can lead to a problem that doctors call "antibiotic resistance." With this problem, a large number of bacteria appear that do not respond to such medications.

A rapid blood test is also used to detect HIV infection. With this analysis, the result is obtained within twenty minutes. Although it is accurate enough, if the result is positive, additional tests are usually done.

Within the framework of different campaigns on the fight against AIDS, such a procedure is proposed to pass to all comers. Express blood test allows you to identify the diseases that causes the bacterium helicobacter pilory, as well as various types of hepatitis and chlamydia. In case of a positive result, it must be confirmed with the help of other tests.

Previously, the definition of paternity was carried out using an analysis of the blood group of parents and a child. This method yielded accurate results only if the man was not the father of the child. But even if the analysis showed that the child was born of a particular man, in fact it could be wrong. In our time, paternity testing is done using DNA. It is also called genetic or PCR analysis. This procedure has high accuracy. If the analysis is positive, and the man is recognized as the father of the child, then the probability of error is not more than 0.01%. If the analysis suggests that the man is not related to the conception of this child, then the reliability of the result is 100%.

For the analysis, the genetic material of the parents and the child is needed. Usually doctors take blood, but you can use a scraping from the mouth or hair. Then the collected samples are brought to the laboratory, where each individual's genetic data is analyzed separately. Upon completion, a detailed report is issued, describing the work performed. It contains information about what samples were made and what the study showed.

Urology blood tests use to assess the health status of men. First of all, it is an analysis of the definition of a prostatic specific antigen (PSA), a protein substance present in cells. Thanks to this analysis it became easier to diagnose prostate cancer at an early stage.

The PSA index reflects any irritation of the gland. For more accurate analysis it is necessary to undergo studies of the rectum and prostate.

For men over the age of 45, it is necessary to take such an analysis every year.
