Standard re-test times are 3-6 weeks, We endeavour to keep that as short as possible but occasionally it does hit the 6 week mark – please email for current lead times.
Re-tests are done on Tuesdays each week. Occasionally you will be asked to complete a new questionnaire before we re-test, but we will not require a new hair sample.
Re-tests are charged pro-rata, based on time taken.
