Does anyone have any experience of using the above controls in total 25OH Vitamin D analysis using the ISYS 25OH Vit D assay by IDS? We do not seem to be acheiving as tight control as we would like with this material and nowhere near as good as we are acheiving with our internal QC pooled serum. Are there any other suitable commercial QC's we could be using - NIST Vit D standard reference materials are currently unavailable according to their website?
