Re: I'm back too and PCR testing From: Dr. Ainsworth (ainsron@sbcglobal.net) Tue Dec 23 08:06:38 2003 Messages sorted by: [ date ][ thread ][ subject ][ author ] Next message: Dr. John Provatopoulos B.Sc.

The HerpeSelect-2 is 99% sensitive and 98% specific. That is in comparison to the Western blot test. They take 3 wks to seroconvert, compared to a delay in the western blot of 6 wks to 3 months. Seroconversion, of course, can be useful in distinguishing a primary from a recurrent lesion. Although cultures are the preferred method to detect virus, the problem with viral culture is that they have up to 50% false negative rates because the virus is only shed from a recurrent lesion for about 2-3 days and require a week to read. Modified culture techniques (ELVIS) provide more rapid turnaround, but don't separate HSV-1 from HSV-2. [Clinical challenges in primary care. AMA. 2002.] >Interesting approach.

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
