The comb tests


1. Press the comb between your finger and thumb so you create a pale spot, then release. The comb should return to its normal colour within 1-2 seconds. If it doesn't, it's an indication of anaemia.

2. A shrunken comb is a sign of dehydratio­n, as is a comb that's suddenly floppy when it's usually upright.
