[sci.med.aids] viral amplification

MADLANSA%FORDMULC.BITNET@mvs.oac.ucla.edu (05/23/91)

I have read in one of messages in  this list that one can be
HIV antibody negative (through ELISA) and be viral positive (through
cell viral amplification).  Can anyone send me more info on this.
Where can you get that cell amplification tests?  Are there research done
for more advanced antibody testing?

Thanks
