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.

Detection of hypomagnesaemia as the cause of unexplained cardiac arrhythmias, neuromuscular disorders, refractory hypocalcaemia.
Patients with clinical features suggesting hypocalcaemia and a normal plasma calcium, or with refractory hypocalcaemia/hypokalaemia, should have plasma magnesium measured.
Hypermagnesaemia may occur in renal failure, but assessment is rarely required.
Monitoring magnesium sulphate during anticonvulsant therapy (especially in pre-eclampsia) or therapy causing renal magnesium loss (eg, cisplatinum).
Decreased levels may be due to increased renal or gastrointestinal loss, or to decreased intake.
Levels fall rapidly in response to reduced intake and may not reflect tissue levels.
Increased levels are usually due to renal failure.
