Being the impatient person I am, I called the Intermountain Lab today to see if Bertrand's urine test result was in. It is not, but it'll be back in 5-7 days. The sample was sent to the Mayo Clinic Laboratory. Since a lot of you have asked, I don't know the full name of the test, but it was called something "saccharides".
Now for some good news! Bertrand's alpha-fetoprotein level is down to 85.4!!! (The normal range is from 0-15, but his level is down from being the 1,000s.) Other news is that his ALT is 318 (normal range is from 5-45) and his AST is 184 (normal range is from 20-60). I believe those two values have stayed fairly constant.
Hopefully, we are converging on a diagnosis. I'll be bugging the Lab again on Tuesday to see if they've received the urine test result.
