0 What is the best method to record Blood Type? 1 Hock_Hin Lee posted 6 Years Ago There are several ways to record/store new information about a person.For example using a New Person Attribute; New Group; New Tag; etc.What would be the best way to record the Blood Type of a person?In our scenario,- not a mandatory field, entered only for people who are willing to donate blood- cannot have more than 1 blood type- want this information to be easily seen on person profile screen- want to be able to see all people with a certain blood type- want to be able to see all people who are willing to donate blood (non-empty field)
