Urine chemistry is a group of one or more tests done to check the chemical content of a urine sample.
Chemistry – urine
How the test is performed
For this test, a clean-catch (midstream) urine sample is needed. For more information, see:
Some tests require that you collect all of your urine for 24 hours.
Your doctor will order certain tests, which will be done on the urine sample in a laboratory.
How to prepare for the test
For detailed information about how to prepare for the test, how the test will feel, risks with the test, and normal and abnormal values, please see the test your health care provider ordered:
urinary aldosteroneexcretion rate 24-hour urine protein Acid loading test (pH) Adrenalin – urine test Amylase – urine Bilirubin – urine Calcium – urine Citric acid urine test Cortisol – urine Creatinine – urine Cytology exam of urine Dopamine – urine test Electrolytes – urine Epinephrine – urine test Glucose – urine HCG (qualitative – urine) Homovanillic acid (HVA) Immunoelectrophoresis – urine Immunofixation – urine Ketones – urine Leucine aminopeptidase – urine Myoglobin – urine Norepinephrine – urine test Normetanephrine Osmolality – urine Porphyrins – urine Potassium – urine Protein electrophoresis – urine Protein – urine RBC – urine Sodium – urine Urea nitrogen – urine Uric acid – urine Urinalysis Urine Bence-Jones protein Urinary casts Urine amino acids Urine concentration test Urine culture (catheterized specimen) Urine culture (clean catch) Urine dermatan sulfate Urine – hemoglobin Urine metanephrine Urine pH Urine specific gravity Vanillylmandelic acid (VMA)
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.
