Optimal Biomarker Ranges
Lab reference ranges for optimal health
Liver and Gallbladder
Tumor
The "normal" range on your lab result indicates what's common, not what's healthy.
Calculated Indexes
Standalone calculators that complement my full interpretation tools
ANI
ALD/NAFLD Index is used for distinguishing Alcoholic from Nonalcoholic Fatty Liver Disease.
C-peptide/insulin
C-peptide to insulin molar ratio is helpful in detecting exogenous insulin use, impaired hepatic insulin clearance and impaired C-peptide clearance by the kidneys.
D/T Bilirubin Ratio
The D/T ratio is used to differentiate between different types of jaundice and liver injury patterns.
FIB-3
The Fibrosis-3 Index is an improved version of the FIB-4, that does not include age. It outperforms both FIB-4 and APRI.
FLI
Fatty Liver Index is one of the best models to predict liver fat content.
HOMA-IR
HOMA1-IR has a poor correlation (r = -0.60) with the gold standard - Glucose clamp index of insulin sensitivity.
LSS
Liver stiffness score is currently one of the best models to predict liver fibrosis. Outperforms FIB-4, APRI and HSI. Trained on NHANES dataset.
QUICKI
QUICKI correlates well (r = 0.78) with the gold standard - Glucose clamp index of insulin sensitivity
R-Factor
R-Factor is used for distinguishing acute liver injury (Hepatocellular from Cholestatic). Often used when drug induced liver injury (DILI) is suspected.
Triglyceride/HDL
Triglyceride-to-HDL ratio is a surrogate marker of insulin resistance, NAFLD and atherogenic dyslipidemia.
TyG
Triglyceride-glucose index is an inexpensive non-insulin surrogate marker of insulin resistance.
TyG-BMI
Triglyceride-Glucose index multiplied by BMI is one of the best models to predict NAFLD.
Please send me relevant research and feedback.

I am particularly interested in research on biomarkers associated with all-cause mortality and on defining optimal reference ranges.
