Biomarker 101: Globulin
Not one protein but a whole category, covering transport proteins and antibodies. The albumin ratio says more than the number.

Biomarker 101: Gamma-glutamyl transferase (GGT)
Sensitive to alcohol, medications and bile flow. Why GGT is most useful read next to ALP rather than alone.
General health
Biomarker 101: Alkaline phosphatase (ALP)
An enzyme from two different places - liver and bone - which is why ALP is never read on its own.
General health
Biomarker 101: Albumin
The most abundant protein in blood. It reflects liver, kidney and nutrition at once - and quietly changes how other results read.

Biomarker 101: Alanine aminotransferase (ALT)
The liver enzyme most specific to liver cells. What raises it, from a heavy training week to a new supplement.
General health
Biomarker 101: Glomerular filtration rate (eGFR)
Calculated from creatinine, age and sex - not measured. Why kidney function is defined by persistence rather than a single reading.
General health
Biomarker 101: Urea (BUN)
A waste product from protein breakdown, sensitive to hydration and diet as well as kidney function.
General health
Biomarker 101: Electrolytes: sodium, potassium and chloride
Sodium, potassium, chloride and bicarbonate are held within remarkably narrow limits. Why small movements matter.

Biomarker 101: Full blood count (FBC)
The most ordered blood test there is, covering red cells, white cells and platelets in one sample.
