These tests are easy and then if you are deficient you can check that your supplements have these 2 minerals. If you are not deficient in iron it is best to avoid supplements that do have iron. Don’t take iron if you don’t need it.
The calcium test:
Hold your arms out straight and thumbs down. The tester pushes moderately down on both wrists once or twice. If the arms are strong and springy then the calcium level is fine. If the arms feel weak or it is easy to push them down because the shoulder muscle feels weak, then the calcium level is low.
The iron test:
Scrape a pure gold ring across the face. If it leaves a gray or black streak, you are low in iron.
