Ultrasound: thickness of subcutaneous fat at specific sites. Less standardised than DXA and operator-dependent. Useful as a supplementary measure but not as a primary method. A partial answer, offered because a partial answer beats none.
DXA precision and the least significant change for lean mass — what changed since — setting out what I have, and where I think it stops being reliable.
A question about measurement precision rather than about physiology.
Two readings, some weeks apart, on the same equipment, differing by an amount that feels meaningful and may not be. I do not know what this instrument's least significant change actually is.
How much difference does there have to be before it is a difference?
Thank you for taking the time. That was more work than a reply usually is.
