Use of Vacuum Blood Collection Tubes for Chickens

25OHD analogues and vacuum blood collection tubes dramatically affect the accuracy of automated immunoassays

Variations in vitamin D quantification methods are large, and influences of vitamin D analogues and blood collection methods have not been systematically examined. We evaluated the effects of vitamin D analogues 25OHD2 and 3-epi 25OHD3 and blood collection methods on vitamin D measurement, using five immunoassay systems and liquid chromatography-tandem mass spectrometry (LC-MS/MS). Serum sample...
