@clandeboye1 I also thought that t I shouldn't be "unfavorable intermediate." However, one of the other health professionals I asked indicated that notwithstanding GS 3+4 = 7, because 8 of 14 cores tested positive, it could be considered unfavorable. If only 6 of 14 were positive, certainly my GS 7 would be "favorable intermediate." Perhaps, even the professionals may look at my GS 3+4 differently? Yes, I read Dr. Walsh's book, the latest edition.
