Liver Function Tests (Pancreas, liver, gallbladder, bile ducts)
A series of blood chemistry tests measuring enzymes excreted by the liver during abnormal functioning due to metastases, obstruction or other conditions. Also called: liver panel. A liver panel may contain any of the following tests. If any one of these tests is outside the normal range of values, the test should be reported as abnormal.
|Alkaline Phosphatase (AIk.Phos.)||20 90 11.1/liter|
|Lactic Dehydrogenase (LDH)||100 190 a/L at 37 degrees|
|SGOT||8 46. a/L (M)
4 35 a/L (F)
|SGPT||7 46 a/L (M)
4 35 a/L (F)
|Leucine aminopeptidase (LAP)||80 200 Goldbarg Rutenburg a/ml (M)
75 185 a/ml (F)
Bilirubin (total) < 1.5 mg/dl
Alpha fetoprotein (Liver) A serum test used as a tumor marker for hepatocellular cancer. Elevated alphafetoprotein levels are also found in certain ovarian and testicular cancers. Note: Observe the date of an alphafetoprotein study carefully. Record a pre operative study only. Alpha fetoprotein is also used as a marker postoperatively to monitor residual tumor. Also called: aFP, AFP, alpha fetoglobulin.
Normal range: Adults: < 15 ng/ml.
CEA (Carcinoembryonic Antigen) (Pancreas, liver) a blood test measuring the presence of an antigen in malignancies arising in entodermal (embryonic) or gastrointestinal tissue. CEA assay is nonspecific for identifying a primary site, but it does indicate the presence of malignancy. Smokers may have an elevated CEA without malignant disease. Normal range: < 2.5 ng/ml. Normal range may vary somewhat according to institutional experience. Levels > 10 ng/ml suggest extensive disease and levels > 20 ng/ml suggest metastatic disease.
CA 19 9 (Cancer Antigen 19 9) (Pancreas, liver) monitors post therapeutic gastrointestinal cancer for recurrence; nonspecific to stomach cancer.
