Who should have a haematology test?
A routine haematology test is a basic test for diagnosis used to test such things as iron level, salt level and thyroid function. The test counts all the different cells and measures haemaglobin. A higher than normal white cell count might mean infection or haematologic malignancy whilst a lower than normal white cell count might mean viral, parasitic infections, malignancy or marrow suppression. A low red count might mean anaemia of numerous causes. It also counts platelets. Blood Test A blood sample is taken from a vein in the arm or a finger-prick or heel-prick (newborns).
