T4 Uptake Test
It will not: An i131 test does not "diagnose" goiter. Goiter is just a term meaning an enlarged and/or nodular thyroid. An i131 scan is a "fucntional" scan. It is used to determine if a nodule within the thyroid is "hot" - picks up a lot of iodine: hyper-metabolic. A "cold" nodule does not concentrate the iodine: hypometabolic. There is a lower risk of thyroid cancer in "hot" nodules. ...Read moreSee 1 more doctor answer

I'm hebs ag negative with a high anti hbs antibody from vaccination. This week's test was reported as hebs ag detected with anti hbs antibody of 513 miu/ml. Lft normal....Scared....Lab error?
Yes: That sounds like lab error. Your hbsab would provide immunity; i'm assuming yoru hbcab (core) is negative; i wouldn't worry, talk to your doctor about a retest if you are concerned, but even if you were infected, there is no reason for treatment at this time. ...Read more

I got a blood test done and the results reflect the following: TSH .328, HDL 32, triglycerides 215, alkaline 23, and blood sugar 107. What you think?
More information: Why were the tests done? Was specimen drawn after an overnight fast? If so the triglycerides are high and so is the blood sugar. Hdl is low. None of the findings are diagnostic of a disease, except, that blood sugar suggests a pre-diabetic state. It is best to discuss the results and treatment with the doctor who ordered the tests. ...Read moreSee 3 more doctor answers

total bilirubin: 1.41 h
ast: 40 h
alt: 100 h
total alk phosphatase: 43 l
serum total protein: 7.1
e.R. Said hepatitis?
Let's try this...: I have only a little bit of the story you've shared. Perhaps it's time to see whether the ast and alt get back to normal after two weeks off alcohol and any not-totally-necessary meds you may be taking. If so, this is the start of a healthier life after alcohol. If not, the workup for virus infections, iron overload, wilson's, autoimmunity & need for exercise can begin. Good luck. ...Read more

HC worker. 1992 Hep B vac, 2004 titer & booster. 2012 labs hep B neg. Labs done last wk; now told that Hep B test is positive?? How can this be?
The vaccine worked: Lab tests aren't perfect and sometimes can be wrong. Or maybe the negative result was from the wrong kind of test. Vaccination makes hepatitis B surface antibody (HBsAb) positive. Tests for surface antigen (HBsAg) or core antibody (HBcAb) remain negative. Most important, you can be sure you are immune and protected by the vaccine -- so no worries. ...Read more
