Blood Tests 4
Common Chemistry Tests
| Question | Answer |
|---|---|
| Alanine Amino Transferase (ALT) | LIVER -->marked elevations point to liver disease; used for monitoring liver treatment |
| Alpha-Fetoprotein (AFP) | LIVER-->increased values in hepatic carcinoma; elevation of AFP in prenatal screening indicates neural tube disorder |
| Alkaline Phosphatase (ALP) | LIVER or BONE-->elevated ALP levels because of biliary obstruction and bone disease |
| Ammonia | LIVER-->increased blood levels indicate cirrhosis and hepatitis |
| Amylase | PANCREAS & LIVER-->increased levels of this enzyme diagnostic of acute pancreatitis; decreased values associated with liver disease' cholecystitis, and advanced cystic fibrosis |
| Aspartate Amino-Transferase (AST) | LIVER or HEART-->increase in enzyme indicative of liver dysfunction; significant increase following myocardial infarction |
| Bilirubin | LIVER-->increased levels in the bloodstream point to red cell destruction and liver dysfunction |
| Blood Gases (ABG) | KIDNEYS, LUNGS-->measures pH, partial pressure of carbon dioxide (PCO2), partial pressure of oxygen (PO2) to evaluate the acid-base balance |
| Blood Urea Nitrogen (BUN) | KIDNEY-->elevated values because of impaired renal function from toxins, inflammation, or obstruction |
| Carcinoembryonic Antigen (CEA) | NONSPECIFIC-->increased in the cases of malignancy, effective in the early detection of colorectal cancer |
| Calcium | BONE-->increased levels associated with diseases of the bone; used in monitoring effects of renal failure |
| Cholesterol (total) | HEART-->indicative of high risk for cardiovascular disease |
| Cortisol | ADRENALS-->elevated levels signify adrenal hyperfunction (Cushings syndrome); decreased levels indicate adrenal hypofunction (Addison's disease) |
| Creatine Kinase (CK) | HEART or MUSCLE-->elevated values point to muscle damage (i.e., myocardial infarction, muscular dystrophy, or strenuous exercise) |
| Creatinine | KIDNEY--> increased levels indicate renal impairment; decreased levels associated with muscular dystrophy |
| Drug Analysis | values monitored to maintain therapeutic range and avoid toxic levels for drugs such as barbiturates, digoxin, gentamicin, lithium, primidone, phenytoin, salicylates, theophylline, or tobramycin |
| Electrolytes (sodium, potassium, chloride, CO2) | KIDNEY, ADRENALS, HEART-->sodium values, increased in disorders of the kidney and adrenals; decreased values of potassium seen in irregular heartbeat; chloride values are increased in kidney and adrenal disorders and decreased in diarrhea |
| Glucose | PANCREAS-->elevated levels signify diabetic problems; decreased values support liver disease and malnutrition |
| Glycosylated Hemoglobin | PANCREAS-->glycohemoglobin level shows what type of diabetic control has occurred over the past several months |
| Gamma-Glutamyl Transferase (GGT) | LIVER--> elevated values assist in the diagnosis of liver problems, specific for hepatobiliary problems |
| Lactate Dehydrogenase (LD) | HEART, LUNGS, LIVER--> elevated levels confirm acute myocardial infarction; chronic lung, kidney, and liver dysfunction |
| Lipase | PANCREAS--> increased levels in acute pancreatitis, pancreatic carcinoma, and obstruction |
| Prostate Specific Antigen (PSA) | PROSTATE-->performed to screen patients for the presence of prostate cancer, monitor progression of disease and the response of the patient to treatment |
| Total Protein | LIVER or KIDNEY-->low levels point to liver and kidney disorders; elevated levels may occur with multiple myeloma and dehydration |
| Triglycerides | HEART-->increased values indicate lipid metabolism disorders and serve as an index for evaluating atherosclerosis possibilities |
| Uric Acid | KIDNEY--> elevated levels found in renal disorders and gout |
| Vitamin B12 & Folate | LIVER-->decreased levels indicate anemias and disease of the small intestine |
