I would like to have a chromagranin a blood test done. Which type of specialist would i be better off going to?

I would like to have a chromagranin a blood test done.  Which type of specialist would i be better off going to?

"a blood test": A blood test for chromogranin is far far less valuable than the expertise of a physician who is knowledgeable in the field of interest. Blood tests have false positives and false negatives, and have to be interpreted in the context of the clinical setting. I suggest you see your doctor; if you are worried about a neuroendocrine tumor, then see an endocrinologist or oncologist. ...Read more

I use to take i pills after intercourse and my dr said to do blood test s.Bhcb type please help i don't think there is a possibility of pregnancy?

They can detect a pregnancy 7-10 days after conception. The best time to take one is when you miss your period. Emergency birth control decreases the risk. ...Read more

How accurate is the blood test for distinguishing between type one and type two herpes?

How accurate is the blood test for distinguishing between type one and type two herpes?

Type specific = good: Type specific herpes tests are great at distinguishing between type 1 & 2. Rarely if someone is highly positive for type 1 w/ a very low positive for type 2, we believe it could be a false positive, even with type specific tests, which are the best tests out there to screen for herpes. If u have a genital sore, immediately see a doc for a swab which reliably distinguishes type 1&2, if positive. ...Read more

Blood test says my blood type is O Positive but on the part where is says Rh factor it says negative. How does that make sense? Mean something else?

It doesn't: It doesn't really, but here's what probably happened: If you're pregnant and getting prenatal labs, in RH negative patients who've had a previous pregnancy it's typical to test for RH factor antibody (an immune response against RH+ blood). This test is not necessary in RH+ women, but it was likely done by routine, and the result, as expected in negative since an RH+ person won't have RH Antibody ...Read more

i have never done blood test before is it important to get

Without : Without clinical scenario (clear cut indication) of why you would actually do a blood test, the results can be meaningless. You need to talk to your physician and discuss the need to do a blood test, rather than purchasing it on groupon. ...Read more
