What’s included
Apolipoprotein B (ApoB)
A protein carried by certain cholesterol-carrying particles; its amount reflects their total number.
HDL Cholesterol (HDL-C)
The amount of cholesterol carried inside HDL particles in the blood.
LDL-C/HDL-C RatioCalc
Calculated comparison of LDL cholesterol to HDL cholesterol, using amounts in the same units.
LDL Cholesterol (LDL-C)
The amount of cholesterol carried inside LDL particles, rather than the number of particles.
Total Cholesterol
The combined amount of cholesterol carried by the major blood lipoprotein groups.
Triglycerides
Fats circulating in the blood that store energy from food the body does not immediately use.
Total Cholesterol to HDL RatioCalc
Calculated ratio of total cholesterol to HDL cholesterol, using measurements in the same units.
Non-HDL Cholesterol (Non-HDL-C)Calc
Calculated by subtracting HDL cholesterol from total cholesterol, capturing cholesterol in the remaining particles.
Total Carbon Dioxide (CO2)
A blood chemistry result used to estimate bicarbonate when assessing the body's acid-base balance.
Chloride
Amount of chloride, one of the blood's major electrolytes, measured in serum or plasma.
Potassium
An electrolyte needed for normal nerve signals, muscle contraction and heart function.
Sodium
A major electrolyte that helps regulate fluid balance and supports nerve and muscle function.
Glucose
The amount of glucose, the body's main circulating sugar and an energy source, in blood.
Fasting
Insulin
A pancreatic hormone that helps move sugar from blood into cells and regulates energy storage.
Fasting
Hemoglobin A1c (HbA1c)
Percentage of hemoglobin with sugar attached, reflecting average blood sugar over roughly two to three months.
Thyroid-Stimulating Hormone (TSH)
A pituitary hormone that signals the thyroid gland to produce thyroid hormones.
Total Calcium
All calcium circulating in blood, including calcium attached to proteins and free calcium.
C-Reactive Protein (CRP)
A liver-made protein that rises in response to inflammation, measured with conventional or high-sensitivity assays.
High-sensitivity C-reactive protein (hs-CRP)
Alanine Aminotransferase (ALT)
A liver-cell enzyme that can enter the blood when those cells are damaged.
Aspartate Aminotransferase (AST)
An enzyme in the liver, muscles and other tissues that can enter blood when cells are damaged.
Alkaline Phosphatase (ALP)
An enzyme found especially in the liver, bile ducts and bones.
Total Bilirubin
The combined direct and indirect forms of bilirubin, a waste product from red-cell breakdown.
BUN/Creatinine RatioCalc
A calculated comparison of blood urea nitrogen with creatinine from the same collection.
Creatinine
A waste product from normal muscle activity that the kidneys mainly remove from blood.
Blood Urea Nitrogen (BUN)
Nitrogen from urea in blood, a waste product formed when the body breaks down protein.
Estimated Glomerular Filtration Rate (eGFR)Calc
An estimate of kidney filtration calculated from blood markers such as creatinine or cystatin C.
Creatinine-based
Albumin
A liver-made blood protein that helps retain fluid and transport other substances.
Albumin/Globulin Ratio (A/G)Calc
A calculated comparison of albumin with globulins, two groups of proteins in the blood.
GlobulinCalc
Calculated amount of non-albumin blood proteins, found by subtracting albumin from total protein.
Total Protein
The combined concentration of albumin and globulins, the main groups of blood proteins.

What people praise
Seeing how everyday choices affect glucose
CGM users value connecting meals and activity with their glucose patterns, helping them experiment with routines and understand their own responses rather than relying on general advice.
