Pancreatic Amylase Test: High Pancreatic Amylase, Normal Range, Pancreatitis, and Pancreas Health
A pancreatic amylase test measures the amylase enzyme that comes mainly from the pancreas, rather than total amylase from both the pancreas and salivary...
Phosphatidylethanol (PEth) Blood Test: Alcohol Biomarker, PEth Levels, Detection Window, and Results
Phosphatidylethanol, usually called PEth, is a blood marker that shows recent alcohol exposure over days to weeks rather than the few hours captured by...
Procollagen III N-Terminal Peptide (PIIINP) Test: High PIIINP, Liver Fibrosis, Normal Range, and Results
Procollagen III N-terminal peptide, often shortened to PIIINP or P3NP, is a blood marker linked to type III collagen formation. Because type III collagen...
Serum Bile Acids Test: High Bile Acids, Normal Range, Cholestasis, Liver Function, and Results

Advanced Lipid Panel Test: ApoB, Lp(a), LDL-P, Particle Size, and Heart Disease Risk
An advanced lipid panel looks beyond standard cholesterol numbers to show more about the lipoprotein particles that carry cholesterol through the blood. A routine...
ApoB and LDL Cholesterol: Interpreting Heart Risk Without Overdoing It
LDL cholesterol and ApoB both describe artery-related cholesterol risk, but they do it from different angles. LDL cholesterol estimates how much cholesterol is carried...
ApoB vs LDL Cholesterol: Which Heart Risk Marker Matters More?
ApoB and LDL cholesterol both describe artery-clogging lipoproteins, but they do not measure the same thing. LDL cholesterol measures how much cholesterol is being...
ApoB/ApoA1 Ratio Test: Normal Range, High Ratio, Cardiovascular Risk, and Results
The ApoB/ApoA1 ratio test compares two major blood proteins involved in cholesterol transport. ApoB is found on particles that can enter artery walls and...
Apolipoprotein A1 (ApoA1) Test: Low ApoA1, Normal Range, HDL Function, and Heart Risk
