Dexa scan accuracy and repeatability

[bossetti]

Hi i want to take a dexa scan because i want to have a record of some snapshot of body composition and muscle distribution trough the seasons not specifically to aim for a specific goal, just collecting data
There is a considerable difference between machines, centers and operators? Eventually there are more reliable methods?

Im also interested in bone density btw

If you want consistency then the more factors that are the same the better. An das most all algorithms' for such things tend to be based off of the average persons body. The leaner of more obese a person gets probably the less accurate they will be to some degree. While they should be able go give a person a fair idea of how things are. I would think as a comparison to earlier results would be where they shine the most.

this might give you some ideas on how accurata and it can be:

Thanks so bod pod and dexa seem pretty precise
Gonna do dxa around march i think

Best to do it in the most consistent manner...like time of the day, previous day's activity , your hydration level, etc etc. Dexa scan is more accurate than inbody scan.
