3140. PCR. Herpes virus type 7 (blood, quantification)
Description
The real-time human herpes virus 7 DNA quantification assay is used to diagnose human herpes virus 7 (HHV-7) infection. PCR can detect infection earlier than immunological methods and provides faster results than culture but does not provide information about past exposure or immunity. Quantitative measurement can provide information about disease regression.
Activation of HHV-7 begins with the multiplication (replication) of the virus in the host cell. Then, in most cases, the host cells die, and new herpes viruses type 7 enter the intercellular space to infect new cells. From here, viral particles enter various biological fluids (blood, urine, cerebrospinal fluid), and glandular secretions, where they can be detected using PCR.
When and who needs the test?
Recommended
- for the differential diagnosis of childhood infections that occur with high fever and rash, often with convulsions;
- for diagnosing chronic fatigue syndrome;
- if you suspect an infectious disease of the central nervous system, the causative agent of which may be herpes virus type 7;
- to monitor viral load to track the progression of infection and response to treatment.
Biological material
- Venous blood
Preparing for a blood test
In order to exclude factors that may affect the test results, we recommend to follow the preparation rules:
- an important condition for laboratory tests is to take blood on an empty stomach.
- 6-12 hours before the test, you should avoid eating, drinking alcohol, smoking, and limit physical activity. Drinking...
