KIDNEY & LIVER
Albumin
Also known as Alb
What it is
Albumin is the most abundant protein in the blood, made by the liver. It carries hormones, drugs, and other molecules.
Why it matters
Albumin reflects protein status, liver function, and hydration. It also affects the interpretation of many hormone and drug tests.
Range GPLX watches for
GPLX watches for albumin within the lab reference range (typically 3.5–5.0 g/dL).
This educational range is not a personal diagnostic threshold. Your physician interprets your result in context of your full biomarker panel, medications, symptoms, and history.
What abnormal values can suggest
If low
A low albumin value can suggest malnutrition, liver disease, kidney protein loss, or chronic inflammation.
If high
A high albumin value most often reflects dehydration.
