Antinuclear Antibody Blood Test
Is an antinuclear antibody blood test result of 1.32 low, medium, or high? Is it something to worry about?
If 1:320, high-ish: Anas are reported as a ratio of how dilute the serum is when the antibody is still detectable, and the lowest ratio reported is usually 1 to 40, written 1:40. Meaning if you dilute the serum 40 fold, you can still find antibody. The next reading is 1:80, then 1:160, then 1:320. The number you write looks like it could be 1:320. That's a significant amount and might cause symptoms. Make appt w doc. ...Read more

Hi my hsbag positive, confirmatory test negative for hep b, also antibody and anticore negative.I did blood test 2 times, same results.Dr said its weird.
Hepatitis B: Not sure what the so-called confirmatory test was, but as a general rule having hepatitis b surface antigen means that you have the disease. You may be in the early window period before the development of antibodies, although anticore antibody usually happens early in the course of the disease and is confirmatory. You might go ahead and take the vaccine and see if the hepb ab becomes positive. ...Read more
Is a HIV negative blood test (antibody test) after 6 month from exposure conclusive? Or should I take another one.
Relax, Don: It's unlikely that your HIV screen would be negative six months after your risky event. You're welcome to repeat in a year or pay a big charge for PCR (which would be absolutely definitive). I suggest you just get on with your life, having learned from your adventure and hopefully loving both more wisely and more meaningfullly. We all make mistakes, little brother. Here's to a happy future. ...Read more
