Some common abbreviations that are used on blood lab printouts include GFR (glomerular filtration rate), AST (aspartate aminotransferase), ALT (alanine aminotransferase), HDL (high density lipoprotein), LDL (low density lipoprotein), ALP (alkaline phosphatase) and AVM (arteriovenous malformation) according to the National Institutes of Health's MedlinePlus and Women's Health Magazine. The AVM abbreviation is used to signify that there is a problem with the circulatory system and that blood is not pumping correctly.
The ALP abbreviation is a signifier that there may be a bone disease or liver disease present in the patient, reports MedlinePlus. The GFR test for kidney damage by looking at the ability of the kidney to handle waste products. If a patient has a low GFR test score then it means the patient's kidneys are not working at the level that they should be. The AST and ALT abbreviations are ways to measure whether or not the patient might have liver disease or improper liver functioning.
Other common abbreviations on blood tests are HDL and LDL. HDL is considered "good" cholesterol while LDL is considered "bad" cholesterol. Patients should look at their ratio of good-to-bad cholesterol when viewing their blood lab results and opt for a lower ratio for optimum health, writes Women's Health Magazine.
