Forum Name: Liver Diseases

Question: End stage hep C.

 Zachmo - Mon Sep 03, 2007 7:43 am

My sister in law is in end stage Hep C. She has been a substance abuser for about 30 years (she is 47 yrs old). She uses enulose to clean the amonia from her blood and she has a shunt/stent in her liver so the blood will pass through (her liver doesn't work). She went through the banding in 1997 and hasn't used alcohol since then, but used crack for a while. Last use of that was April 2006. She has court ordered drug screens. Her THC levels have been increasing by several points for her last three screens. She states she hasn't used since mid to late June 2007. Is there any medical reason for the levels to go up?

User avatar Hi Zachmo,

It depends on the type of test used to test for the THC. Simple urine dips can sometimes have interfering substances that can give a false positive. More sophisticated testing using gas chromatography and mass spectrometry are much less likely to give a false positive.

If needed the GC/MS testing can be used to confirm the presence of THC in cases of possible false positives.

Best wishes.
