What is a marrow PCR test?

Question
Hello doctor,
Can you tell me what is a marrow PCR test? Do you have to have a marrow aspiration to take it for testing? If I had to have a bone marrow puncture, how would it affect me?

Hello,
With the question “What is a marrow PCR test? ", the doctor would like to answer as follows:
The doctor understands that you are asking CSF PCR, because this is a much more common test order than bone marrow PCR. The PCR test of the cerebrospinal fluid requires aspiration and aspiration of the cerebrospinal fluid, then the cerebrospinal fluid will be biochemically tested to check the properties of the cerebrospinal fluid, cytology to detect cells in cerebrospinal fluid and PCR of cerebrospinal fluid to find out the cause of bacteria and viruses that cause encephalitis and meningitis!
In most cases, lumbar puncture causes no problems or dangerous complications. The risk of infection from this procedure is also very rare and is greatly reduced because an antiseptic is used to clean the patient's back before the procedure.
Patients may occasionally experience mild lower back pain after a lumbar puncture that resembles a bruise, but this usually resolves on its own. Another common side effect that can be experienced is headache. If the patient has a bleeding disorder, there is a risk of bleeding, nerve damage and spinal cord damage, but this is very rare.
If you still have questions about the marrow PCR test, you can go to a hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
