Response from Dr. Young
Thanks for your post.
This is really just a lab requisition issue- both tests measure HIV viral loads; they differ only by what is the lower limit of detection. In your case, both tests read undetectable; indeed for most patients, a viral load less than 400 indicates that the viral load is also less than 50. Having the ultrasensitive test provides an extra degree of confidence, but I wouldn't think that you need to have the test repeated.
As for your CD4 and CD8 cells- these changes are essentially insignificant. I'd interpret the findings to say that your immune system hasn't changed much between the two tests.
I hope this helps, BY
