PCR diagnosis or diagnosis based on the polymerase chain reaction is one of the newest techniques of modern molecular biology. With PCR analysis one can detect the presence of any infection and there is no risk that the result will be reduced to zero.
What infections can be detected by PCR analysis
There is a wide range of infections, which can be determined by laboratory method of diagnosis. The meothod is widely used in gynecology, urology, physical therapy, pulmonology, oncology, gastroenterology, hematology, and other fields of medicine.
Thus, by analyzing the PCR one can identify the following infections:
- HIV and AIDS.
- Hepatitis virus.
- Herpes infection of the first and second type.
- Sexually transmitted infections, such as chlamydia, ureaplasma, trichomoniasis , and others.
- Papillomovirusnoy infection and other oncogenic viruses.
- Tick-borne encephalitis.
- Candidiasis and many other fungal infections.
- Helicobacter and other infections.
Advantages of PCR over other methods of diagnosis
- Rapid detection of the causative agent.
- The almost complete absence of false positives.
- The ability to detect infection even in the presence of a single cell parasite.
- One sample of biological material can help determine the number of pathogens.
- The results obtained within 4-5 hours.
- The ability to detect infection before the onset of symptoms, which greatly increases the effectiveness of treatment and reduces the risk of complications.
How to prepare for the analysis of PCR
The accuracy of the result of this analysis is almost always absolute, if certain rules before taking the blood are followed. Thus, in order to properly prepare for performing PCR analysis, it is necessary:
- Not to have sex one the day before the delivery of blood.
- Quit eating or drinking before blood test, that is, it is essential to perform blood test in the morning, being fasting.
- If you need urine to be analysed, you should collect the first morning portion, making sure it is always collected in a special sterile container.
