|
serum alkaline phosphatase
|
Increases with biliary obstruction and cholestatic hepatitis, also bone disease, renal disease, hyperthyroidism, hyperparathyroidism. (13-39 U/ml)
|
|
|
|
aspartate amino transferase (AST)
|
Increased with hepatocellular injury, but also cardiac, skeletal muscle, lung or kidney injury (non-specific). (5-40 U/ml)
|
SGOT
|
|
|
alanine amino transferase (ALT)
|
Increases with hepatocellular injury, especially due to viral and drug induced injury. (5-35 U/ml)
|
SGPT
|
|
|
lactate dehydrogenase (LDH)
|
Elevated with hypoxic and primary liver injury, also with MI, renal disease, musculoskeletal disease, pernicious anemia (200-500 U/ml)
|
|
|
|
Indirect (unconjugated) serum bilirubinIndirect (unconjugated) serum bilirubin
|
Increases with hemolysis (< 0.8 mg/dl)
|
|
|
|
direct (conjugated) serum bilirubin
|
Increases with hepatocellular injury or obstruction (0.2-0.4 mg/dl)
|
|
|
|
total serum bilirubin
|
Increases with biliary obstruction (<0.1 mg/dl)
|
|
|
|
albumin
|
Reduced with hepatocellular injury (3.5-5.5 g/dl)
|
|
|
|
globulin
|
Increases with hepatitis (2.5-3.5 g/dl)
|
|
|
|
albumin/globulin (AG) ratio
|
Ratio reversed with chronic heptitis or liver disease (1.5:1 to 2.5:1)
|
|
|
|
total T4
|
measure of bound and unbound T4
|
|
|
|
free T4
|
measures free or active t4. This is the best measure of hypo - and hyperthyroidism, and avoids interpretive problems in patients with altered thyroid binding. In past was difficult to perform, routine now.
|
|
|
|
sTSH
|
sensitive TSH, measures thyroid stimulating hormone produced by pituitary. Combination of sTSH and FT4 can diagnose different types of thyroid disorder.
|
|
|
|
fasting blood glucose
|
Best test for diabetes. 2 hour post prandial serum glucose can be used to confirm.
|
|
|
|
hemoglobin A1C
|
Measures amount of glucose incorporated into HgbA1c, and reflects long term blood glucose control.
|
|
|
|
hematocrit
|
% of RBCs in blood, low values indicate anemia, and can be due to decreased number or size of RBCs or increased plasma volume.
|
|
|
|
RBC count
|
indirect estimate of hemoglobin content.
