Thyroid Stimulating Hormone (Dried Blood Spot)

Test information: Dried blood spot TSH is used for the monitoring of Downs Syndrome patients, and patients (children and adults) with other disabilities that may make taking a blood sample for thyroid testing particularly difficult. TSH only will be reported as fT4 cannot be measured on a dried blood spot. Please note that TSH testing done as part of the newborn screening service is provided by the regional screening laboratories, with the guthrie cards sent directly to them.
