A patient has elevated liver enzymes. What is the likely etiology of the elevation? AST 150 & ALT 642
Hepatitis
A diagnosis of hepatitis is far more common when the ALT is elevated. AST becomes the dominant liver enzyme when the patient has consumed a substance that causes the liver to be damaged. Examples of this are acetaminophen, alcohol, and drugs
90
A patient has the following lab results: anti-HCV: reactive. This means?
More data are needed
The anti-HCV is a screening test. A patient who has a reactive screen for hepatitis C may have the disease, but more data are needed to determine this. Once the screen is reactive, a confirmatory test should be performed. The confirmatory test is the HCV RNA. If it is detectable, it indicates past or current infection with hepatitis C. If undetectable the HCV RNA indicates that the screen was a false positive
91
A 44-year-old patient has the following lab results. How should they be interpreted?
HBsAG: negative
anti-HBc: positive
anti-HBs positive.
Patient had hepatitis
This patient has a negative hepatitis B surface antigen (HBsAg) therefore he does not have active hepatitis B. The patient has a positive hepatitis B surface antibody (anti-HBs) therefore he is considered immune. The patient also has a positive hepatitis B core antibody (anti-HBc) therefore he is immune because he has had hepatitis B.
92

may only blead with trauma (joint and muscle hemorrhages are common in mild-mod hemophilia, result in disability )
