An immunoassay premium plus control is designed to monitor the accuracy and precision of up to 54 analytes including 25-OH Vitamin D and 1-25(OH)2 Vitamin D.
Specific target values are also provided for a wide range of fertility hormones, thyroid hormones, steroid hormones, kidney function tests, therapeutic drugs, and tumor markers. The inclusion of routinely run tumor markers and parameters such as intact parathyroid hormone (PTH) allows quality control practices to be simplified by dramatically reducing the number of controls used in the laboratory with the added benefit of cost and time savings.
The Acusera immunoassay premium plus control is being offered by Randox (Crumlin, United Kingdom). It has a shelf life of up to four years and is suitable for long-term quality control (QC) monitoring. It can significantly reduce the costs and problems associated with changing lot numbers.
In addition to low Vitamin B12 levels, the Randox Immunoassay Premium and Premium Plus controls contain ultra low levels of ferritin and thyroid stimulating hormone (TSH) as well as other vitamins. The control also contains many of the routinely run tumor markers including alpha-fetoprotein (AFP), CA15-3, CA19-9, CA-125, CEA, prostate specific antigen (PSA), and Free-PSA.
Vitamin D can also be found in the Randox RIQAS Immunoassay EQA program. RIQAS (Randox International Quality Assessment Scheme) is a large global EQA scheme with more than 20,000 participants in over 100 countries worldwide.
