Tosoh Launches Vitamin D Assay

Tosoh Bioscience, Inc. introduces the ST AIA-PACK 25-OH Vitamin D assay for use on Tosoh AIA System Analyzers*. Vitamin D measurement is intended as an aid in the determination of Vitamin D sufficiency. 25-OH Vitamin D is known as the best indicator of Vitamin D status, indicating Vitamin D deficiency. It has been 

reported that Vitamin D deficiency is associated with several diseases, including osteoporosis, cancers and cardiovascular diseases.
Utilizing Tosoh’s unit dose test cup reagent technology, ST AIA-PACK 25-OH Vitamin D has an assay time of approximately 40 minutes. Single, unitized test cups require no pre-mixing, no pre-measuring and no on-board refrigeration. Dry reagent format ensures 90-day calibration stability for minimal waste and cost effective testing. Test cups are bar-coded for easy identification and inventory management. 

ST AIA-PACK 25-OH Vitamin D is designed for In Vitro Diagnostic Use Only for the quantitative measurement of total 25-hydroxyvitamin D (25-OH Vitamin D) in human serum, Na heparinized or EDTA plasma on Tosoh AIA System Analyzers. The ST AIA-PACK 25-OH Vitamin D has an assay range of 4 to 120 ng/mL. The antibody has equimolar affinity for both 25-OH Vitamin D2 and D3 and measures the total 25-OH Vitamin D. The 90-day calibration stability makes it feasible to run this test even with low volumes.
