Whoops. There goes the mind :) With the proper math, the second example should have read:
"If it's non-detectible at 8 weeks he can cut that down to 44 weeks of treatment."

That's an EXCELLENT four-week viral load. Have the test repeated at 8 weeks and 12 weeks. As rev says, once it's non-detectible add an additional 36 weeks. So if it's non-detectible at 12 weeks then your husband treats for 48 total. If it's non-detectible at 8 weeks he can cut that down to 42 weeks of treatment. The reason treatment is continued past non-detectible is that the virus still remains in minute quantities. It takes that much time for the drugs to hunt down and kill every last virus. :)
"Non-detectible" defined by most studies means under 50 IU/ml. So make sure your doctor uses a test with at least that sensitivity.
Again, that test is very good news and hopefully your husband will have a successful outcome.
