A blood test is performed via a blood test kit sent to you in the post. This is a finger prick blood test. Upon receipt of the blood sample the testing is performed according to the categories listed below. This is useful particularly for those who are not as of yet sure they would like the therapy but would like to see what the testing finds.  A questionnaire is sent to you via email to be completed prior to us performing the blood test. Once the sample has been received, you will get the results within 10 days (These will be sent to your email address unless you request otherwise). We are here to answer any questions should you have any. Please note this is not designed to replace a visit to the doctors or a blood test done through the NHS should you have major health concerns. Please also note that is a blood test done using cellular testing.
