Bone & Muscle
2
BMD Z-Score
A number from a bone density scan that compares the mineral content of your lower spine to what is typical for people your age and sex.
BMD T-Score
A measurement from a bone density scan that compares the strength of your bones to that of a healthy young adult, used to detect thinning bones before they break.
Body Composition
15
ALMI
A measurement of how much muscle you carry in your arms and legs, scaled to your height, used to flag muscle loss before it leads to weakness or disability.
VAT Mass
Fat stored deep inside the abdomen wrapped around your internal organs, which behaves very differently from the fat sitting just under your skin.
FFMI
A measurement of how much muscle, organ, and bone tissue you carry relative to your height, separating lean body mass from body fat.
Total Body Fat
The share of your body weight that is fat rather than muscle, bone, and water. It is usually measured by a body-composition scan, not a blood test, and helps show risk that weight alone can miss.
Total Lean Mass
A body composition measurement of all non-fat, non-bone tissue in the body, mostly muscle, that reflects how much functional reserve you carry.
Lean Mass (Arms)
A measurement of the non-fat tissue in your arms, used as a regional indicator of upper-body muscle quantity.
Lean Mass (Legs)
A measurement of the muscle and other non-fat, non-bone tissue in your legs, used as a direct read on how much working muscle you carry below the waist.
Lean Mass (Trunk)
Lean Mass (Head)
Total Fat Mass
The combined weight of all the fat stored throughout your body, a measure of how much of you is fat rather than muscle, bone, and water.
Fat Mass (Arms)
Fat Mass (Legs)
Fat Mass (Trunk)
Fat Mass (Head)
BMI
A calculation based on your weight and height that estimates how much body fat you carry, used to screen for weight categories that raise your risk of heart disease, diabetes, and other chronic conditions.
