Vital Organ Function Markers
Blood markers assessing liver function, kidney function, and electrolyte balance including ALT, AST, creatinine, and electrolytes.
About Vital Organ Function Markers
Vital organ function markers assess the health and function of your major organs, primarily the liver and kidneys. Liver function tests include enzymes (ALT, AST, GGT, ALP) and proteins (albumin, total protein, bilirubin). Kidney function is assessed through creatinine, BUN, and calculated eGFR. Electrolytes (sodium, potassium) are also monitored for proper cellular function.
These markers help detect liver disease, kidney dysfunction, and electrolyte imbalances early, often before symptoms appear. They're essential for monitoring medication effects, assessing hydration status, and ensuring vital organs are functioning optimally.
All Vital Organ Function Markers
Albumin
g/L
The main protein in blood plasma, produced by the liver.
Learn moreALP (Alkaline Phosphatase)
U/L
An enzyme found primarily in the liver and bones.
Learn moreALT (Alanine Transaminase)
U/L
ALT (Alanine Transaminase, also written ALAT or SGPT) is an enzyme concentrated in the liver. When liver cells are damaged, ALT leaks into the bloodstream, so it is the single most liver-specific enzyme on a standard Liver Function Test (LFT). It is often interpreted alongside AST, GGT and ALP to build a picture of liver health.
Learn moreAST (Aspartate Transaminase)
U/L
AST (Aspartate Transaminase, also written ASAT or SGOT) is an enzyme found in the liver, heart, skeletal muscle and red blood cells. Because AST exists in multiple tissues, it is less liver-specific than ALT. Pathology labs report AST as part of the standard Liver Function Test (LFT) panel.
Learn moreBilirubin
μmol/L
A yellow pigment produced during the breakdown of red blood cells.
Learn moreBUN (Blood Urea Nitrogen)
mmol/L
A waste product filtered by the kidneys.
Learn moreCreatinine
μmol/L
A waste product produced by muscles and filtered by the kidneys.
Learn moreGGT (Gamma-Glutamyl Transferase)
U/L
An enzyme found in many tissues, especially the liver.
Learn morePotassium
mmol/L
An essential electrolyte for heart and muscle function.
Learn moreSodium
mmol/L
The main electrolyte in blood that regulates fluid balance.
Learn moreTotal Protein
g/L
The sum of all proteins in blood plasma, including albumin and globulins.
Learn moreUric Acid
μmol/L
A waste product from the breakdown of purines.
