It depends upon your appointment time re - the true reading'. A true reading would be the earliest possible appointment, fasting (you can drink water) and allow a gap of 24 hours between your last dose of levo and the test. Early a.m. testing causes the TSH to be at it's highest point and drops throughout the day, meaning that some doctors will adjust the dose due to the TSH alone. You can take vitamins when you wish. Some have to be taken with food.
My appointment is at 10.00 so should be okay
Personally I always arrange my own private blood tests (nice & early in morning) beforehand and take the results along with me. Otherwise the appointment can just be ......"well until we get your blood tests back we don't know how to proceed"
But you do take the risk of upsetting them, if this is NHS appointment. Private appointment it's seen as normal procedure
You need to stop vitamin B complex 4-5 days prior to any thyroid blood test as biotin in B complex can falsely affect results
