Spoke too soon

I may have spoken too soon about DH feeling better.  This weekend has not been as good.  Yesterday he seemed quite ill when he awoke from his nap (he always takes that daily nap - I know he needs it).  Today he seemed quite ill before he "went down" (he's down right now).  We're waiting for the results of the blood test.  Apparently the lab screwed up, so he had to go yesterday morning to get his blood taken again.  The results of this test will be the next test for the virus (next after the 4-week test).  Hoping for those wonderful words "virus undetectable" of course.
