Remarks | The Haematinic panel of tests are often undertaken on routine Immunoassay and spectrophotometric platforms used by Medical Biochemistry Departments and are no longer confined to specialist Haematology Departments. Ferritin is used as an indicator of iron status. A ferritin of <30ug/L is indicative of iron deficiency, whilst an elevated level (>400 ug/L) is indicative of iron overloading such as haemosiderosis or haemochromatosis. Elevated ferritin values are also encountered in certain tumours: acute leukaemia, Hodgkins disease and carcinoma of the lung, colon, liver and prostate. Investigation of folate deficiency may be indicated when nutritional, macrocytic or megaloblastic anaemias are suspected. Since a deficiency of either vitamin B12 or folate can cause megaloblastic anaemia, both tests are indicated in order to diagnose the aetiology of anaemia. Four liquid human serum samples are distributed monthly, with a minimum of 48 samples distributed over the year covering a wide clinically relevant range. The material is prepared from endogenous samples donated by polycythaemic, hemochromatosis, renal patients and healthy volunteers. The samples consist of a panel of 10 samples distributed on a number of occasions over that period which are used to assess both laboratory and method performance, including linearity, bias, within and between batch imprecision. Additional challenging samples spiked with iron traceable to NIST SRM #928 are distributed to assess the performance at mild and severely toxic levels. Key Features: - Commutable, endogenous samples from patients and volunteers. - Challenging samples assess the performance at mild and severely toxic levels of iron. - Liquid human serum samples require no pre-analytical preparation. - Sample cover a wide clinically relevant range. - Scoring based on Milan Model 3 performance specification.
