Does my blood test report indicate any abnormalities?
Q: I recently got a routine blood test done and was told that my T4 - 2.22 (normal 1.17); TSH - 0(normal 0- 0.34); and my SGPT - 114, SGOT - 47. Platelets are 516000, Hb, RBC normal. I do not have any symptoms of hyperthyroidism or liver disease. Are liver and thyroid levels correlated? What further tests do I need to get done? Do I need life long medicines for hyperthyroidism? What could be the cause of elevated platelet count?
A:You must realise that isolated abnormalities of test results leads to needless worry and waste of money as one treats an individual who is ill and not an abnormal test result. You have not mentioned why these tests were ordered and what was the indication for them? There are many causes for each of these tests to be abnormal and it is not possible to view this in isolation. The measurement of T4 level aids in the assessment and diagnosis of thyroid status. Elevated T4 values are characteristically seen in patients with overt hyperthyroidism, while T4 levels are generally depressed in patients with overt hypothyroidism. The enzymes AST (SGOT) and ALT (SGPT) are sensitive indicators of liver damage due to many causes. But it must be emphasized that higher-than-normal levels of these liver enzymes should not be automatically equated with liver disease. They may mean liver problems or they may not. The interpretation of elevated AST and ALT levels depends upon the whole clinical picture and so it is best done by doctors experienced in evaluating liver disease. Abnormally high platelet levels (thrombocytosis) may indicate either a benign reaction to an infection, surgery, or certain medications; or a myeloproliferative disease in which the bone marrow produces too many platelets too quickly.
