| Remarks | Four levels of liquid human serum samples are distributed monthly, with a minimum of 48 samples distributed over the year covering a wide clinically relevant range for steroid, thyroid function and fertility profiles. The material is prepared from endogenous samples donated by both patients and healthy volunteers, with the addition of purified source of T4, T3, TSH, oestradiol, progesterone and cortisol to enhance the pathological range for certain samples. Challenging samples are distributed to assess the performance at clinical decision points as well as effects of interferences such as turbidity, icterus, heterophilic antibodies along with an ongoing programme of interpretative exercises. Macroprolactin exercises are conducted periodically to assess current laboratory practice in Macroprolactin investigation. Key Features: ✓ Commutable, endogenous samples including those that challenge immunoassays such as sample with Macroprolactin and antibody interferences, and samples that mimic ovarian hyperstimulation syndrome. ✓ Liquid human serum samples requiring no prior preparation. ✓ Single donor samples are used wherever possible to minimise any matrix effects. Programme assesses both laboratory and method performance, including bias, within and between batch imprecision. ✓ Trueness is also assessed for Testosterone, Cortisol and Progesterone using high metrological order Reference measurement systems. ✓ Includes Calculated parameters. ✓ Scoring based on Milan Model 3 performance specification.
