Common Blood Chemistry Tests(Kali Dansingburg)
| Question | Answer |
|---|---|
| Albumin aminotransferase (ALT) | Detects liver disease Reference range:45 U/L or less |
| Alkaline phosphate (ALP) | Assists in dx of liver & bone disease Reference range:25-140 U/L |
| Aspartate aminotransferase (AST) | Detects tissue damage Reference range:40 U/L or less |
| Blood urea nitrogen (BUN) | Screens for renal disease, especially glomerular functioning Reference range:7-25 mg/dl |
| Calcium (Ca) | To assess parathyroid functioning & calcium metabolism & evaluate malignancies Reference range: 8.5-10.8 mg/dl |
| Chloride (Cl) | Assists in diagnosing disorders of acid-base & water balance Reference range:96-109 mml/dl |
| Cholesterol (Chol) | To screen for atherosclerosis related to coronary artery disease; secondary aid in study of thyroid & liver functioning Reference range: (desirable) Less than 200 mg/dl |
| Low Density Lipoprotein (LD) | Complex molecules found in cholesterol; picks up cholesterol from ingested fats & the liver, delivers to blood vessels & muscles; aka bad cholesterol Reference range: (optimal) less than 100 mg/dl |
| High Density Lipoprotein (HDL) | Complex molecules found in cholesterol; removes excess cholesterol from the cells & carries it to the liver to be excreted; aka good cholesterol Reference range: (optimal) 60 mg/dl |
| Creatinine (Creat) | Screening test of renal functioning Reference range: 0.6-1.5 mg/dl |
| Globulin (Glob) | To identify abnormalities in rate of protein synthesis & removal Reference range: 2-3.4 g/dl |
| Glucose | To detect disorders of glucose metabolism Reference range: varies |
| Fasting blood glucose (FBG) or Fasting Blood Sugar (FBS) | Blood sugar done with patient having being NPO for 12 hours prior to test. Reference ranges: Normal 70-99 mg/dl |
| 2 hour postprndial blood sugar (2-hr PPBS) | Often performed on patients with DM to eval progress & regulate tx OR as routine screening to detect DM. The patient fasts after midnight; breaks contain 100 g of carbs OR drinks a glucose solution. Reference range: Less than 140 mg/dl |
| Oral glucose tolerance test (OGTT) | Provides more detailed info about the ability of the body to metabolize glucose by assessing the insulin response to a glucose load. Reference range: 139 mg/dL or less |
| Lactate dehydrogenase (LD) | Assists in confirming myocardial or pulmonary infarction; also used in differential dx of MD and pernicious anemia Reference range: 240 UL or less |
| Phosphorus (P) | Assists in proper eval & interpretation of calcium levels; used to detect disorders of endocrine system, bone diseases & kidney function Reference range: 2.5-4.5 mg/dL |
| Potassium (K) | To dx disorders or acid-base & water balance in the body Reference range: 3.5-5.3 mmol/L |
| Sodium (Na) | To detect changes in water & salt balance in the body Reference range: 135-147 mmol/L |
| Total bilirubin (TB) | To evaluate liver functioning & hemolytic anemia Reference range: 0.2-1.3 mg/dL |
| Total protein (TP) | Screens for diseases that alter protein balance & assesses state of body hydration Reference range: 4.5-12 ug/dL |
| Triglycerides (Trig) | To evaluate patients with suspected atherosclerosis Reference range: Less than 150 mg/dL |
| Uric acid (UA) | To evaluate renal failure, gout, & leukemia Reference range: Male 3.9-9 mg/dl Female 2.2-7.7 mg/dl |
