Lab Tests Beginning With L
7 tests in the Lab Values reference begin with the letter L. Every name links to a page with its typical adult range in both unit systems, plain-language notes on high and low results, and preparation notes where they apply.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
