The main purpose of this Manual is to provide useful guidelines for the selection of pathology tests and to facilitate interpretation of results.
Contains a comprehensive listing of all genes from the Human Gene Nomenclature Committee (HGNC) database alongside laboratories and tests available in the country.
A manual for the process of macroscopic dissection in Anatomical Pathology laboratories.

Thyroid stimulating hormone. Free T4 if pituitary disease is suspected. Monitoring: TSH should be maintained within the reference interval ie, thyroid replacement therapy should not cause TSH suppression (unless history of differentiated thyroid cancer).
Patients should not be tested at less than monthly intervals, especially if the thyroxine dose has been altered, as the half life of thyroxine is approximately one week.
Testing at 6 monthly intervals is usually sufficient.
Patients with a history of thyroid disease should always have TSH performed prior to anaesthesia/surgery.

If thyroidectomy was performed for differentiated thyroid carcinoma, thyroxine therapy should be adjusted and suppression of TSH levels may be necessary depending on staging.
Hypothyroidism should be detected on Neonatal screening.
See also Neonatal screening.
Thyroid radioactive iodine uptake studies may be indicated to establish the diagnosis of thyroid aplasia/hypoplasia or to detect ectopic thyroid tissue.
Peripheral resistance to thyroid hormone
Thyroid stimulating hormone and Free T4 are both elevated.
