Blood Test Codes

Blood tests are performed to determine the biochemical and physiological state of the blood, which can determine if a patient is ill, if there is an imbalance in a mineral, if drugs are working or present, or if organs are functioning properly. There are many test abbreviations, so referring to a list of blood test codes can be very helpful.

Common Blood Test Codes

Blood Test Code

Definition

CBC: Complete Blood Count

This is one of the most common tests administered, which measures the cell count in the blood and the ratios and weights of blood components by comparing white and red blood cell counts, hemoglobin, hematocrit, and corpuscular volume.. It helps doctors determine if a patient is affected by infection, anemia, blood cancers, immunity issues, or platelet problems.

BMP: Basic Metabolic Panel

This series of tests is used to measure chemicals present in the blood. The test is administered on the plasma and measures electrolyte levels, glucose, calcium, and other chemicals. It is used to determine a patient’s overall health and if there are any underlying imbalances causes various health problems.

CK: Creatine Kinase Tests

This measures an enzyme in your body that is produced when the heart is injured. This test is used when a patient has a heart attack. It indicates the severity of the heart attack.

LDL and HDL

This tests measures the amount of bad (LDL) and good (HDL) cholesterol in the blood. If results are out of the norm, your doctor will likely suggest dietary changes and potentially cholesterol medication.

CRP: C-Reactive Protein Test

This test measures how much protein in the blood which indicates if a patient has inflammation and is at risk for a heart attack. Result can be used to encourage a patient to make lifestyle changes to reduce his or her risk.

TSH: Thyroid Stimulating Hormone Test

This test is used to diagnose thyroid disorders, such as when the thyroid is underactive or there is a problem with fertility.

AST: Asparate Aminotransferase

This measures an enzyme found in the blood that rises when an injury occurs in the body’s tissue or an organ. It helps a doctor determine if there are internal injuries.

Blood Test Reference Range

This chart indicates normal levels for blood test results. It applies to adults, so adjustments will be needed if testing a child. If your test results indicate something abnormal, your doctor will discuss potential causes and whether or not changes or medications are needed to restore levels to normal.
