The most common abbreviation used in blood test results is FBC, or full blood count, according to NHS Choices. This is also referred to as a complete blood count, or CBC.
An FBC test detects low or high hemoglobin, platelet and blood cell levels and gives health care professionals a better sense of an individual's overall health, explains NHS Choices. Another common abbreviation on blood tests is ESR, which stands for erythrocyte sedimentation rate. This test is used to determine inflammation levels in the body. By observing how fast the red blood cells in the sample fall, health professionals can determine the extent of inflammation in the body.
A C-reactive protein test shows up as CRP on a lab report, notes NHS Choices. CRP is a chemical released by the liver that indicates inflammation within the body.
Other common test abbreviations concern the thyroid. TSH stands for thyroid-stimulating hormone. This test detects an overactive or underactive thyroid along with detecting levels of thyroxine and triiodothyronine, reports NHS Choices.
Individuals should consult with a health care professional whenever possible to maximize their understanding of test results, as normal ranges for testing vary by age, gender, fitness and other factors, according to NHS Choices.
