Have IgG and IgM for CMV but PCR not detected. Pos rmsf IgM neg igg. Bands in CSF mri/white matter foci. Many symptoms possible ms. No real answers?

Have IgG and IgM for CMV but PCR not detected. Pos rmsf IgM neg igg. Bands in CSF mri/white matter foci. Many symptoms possible ms. No real answers?

Uncertainty: I am unclear as to what is really going on. Appears that you have immune activity in the central nervous system. You have some cross-reactivity in the serum for CMV and rickettsial infection. Don't think that need to add another disease to the picture. Best to discuss with your doctor or get a second opinion from another specialist. ...Read more

Polymerase Chain Reaction (Definition)

Polymerase chain reaction is a method of finding a specific piece of dna and copying it over and over again until there is enough to study. The technique allows a scientist to detect very small amounts of dna in a swab sample then reproduce enough of it to study it. It is very sensisitive for detecting the presence of certain bacteria and is also used in doing other ...Read more

Had HSV DNA PCR test with CSF? Negative. Also had HSV 1/2 antibody (IgM), IFA with reflex to Titer, CSF. Negative. Can I still have HSV 1 or 2?

Had HSV DNA PCR test with CSF? Negative. Also had HSV 1/2 antibody (IgM), IFA with reflex to Titer, CSF. Negative. Can I still have HSV 1 or 2?

No HSV in CNS: With these tests, you're obviously under a doctor's care, maybe including an infectious diseases specialist or neurologist. They can answer these questions best. But these results effectively rule out HSV infection of your central nervous system. Something else is causing the problem. That said, the HSV IgM test is notoriously unreliable. You probably also had an IgG test, probably negative. ...Read more

What exactly is a CSF culture & what is its purpose? Is it difficult to perform and does it take longer than blood cultures for a result to come back?

What exactly is a CSF culture & what is its purpose? Is it difficult to perform and does it take longer than blood cultures for a result to come back?

Similar to blood: A CSF culture is when you take a sample of CSF (usually from a lumbar puncture which samples the CSF from the spinal canal in the lower back - so yes a bit more difficult to perform but still pretty routine) and culture it to see if there are bacteria (or sometimes viruses) growing in it, usually to look for meningitis. It takes the same amount of time as a blood culture (48 hours). ...Read more

What are the steps for HIV testing using a pcr?

What are the steps for HIV testing using a pcr?

Steps?: I'm not sure what you're asking. The "steps" are that you have your doctor order it, go to the lab, hold our your arm, and get the blood drawn. The more complicated question has to do with the indication for the test: who needs it and when. If that's what you're asking, please repost the question. ...Read more

Is HIV PCR DNA test after 9 weeks conclusive enough?

Is HIV PCR DNA test after 9 weeks conclusive enough?

HIV PCR testing: Yes. This excellent new way of testing viruses is very sensitive. It is thought that the HIV pcr dna test can narrow the window to 14 to 21 days post exposure.

A negative test at 9 weeks post exposure means you do not have hiv. ...Read more
