Monika, yes we do our blood tests at home. My family has been doing our phe levels at home since I was probably two or three months old. It is definitely easier than driving to the lab.
You are seeing Jessica right? If so give her a call or an email and let her know you would like to give this a try (although I think she's still on break at the moment). She can give you the filter paper, envelopes, and lancets to do the blood tests. Have you done Matthews blood tests on your own before?
