GL200 - Studying blood

Updated from section 14 in the CLEAPSS Handbook, this offers practical advice on obtaining and studying blood, including human blood. It describes safe procedures for taking human blood and dealing with it after study. It also suggests a number of investigations which can be undertaken with fresh blood.
In conjunction with this guide is a model letter to parents seeking permission for their child to take a sample of their own blood.
