In this publication iCheck Carotene for the analysis of ß-carotene in whole blood was compared to the golden standard method HPLC.
In 166 cows ß-carotene levels in plasma and blood were determined by HPLC as standard and compared with iCheck. As a result no differences were observed between both methods either measured in plasma or in blood (HPLC plasma vs iEx™ plasma: 4.23 vs 4.49 mg/L and HPLC plasma vs iEx™ blood: 3.46 mg/L vs. 3.67 mg/L). Both methods showed a very good agreement based on correlation coefficients of r2> 0.98. iCheck Carotene can therefore be used as a fast and precise method to assess blood levels of ß-carotene within minutes.

(German:) Der positive Einfluss von ß-Carotin auf die Fruchtbarkeit von Milchkühen ist seit langem bekannt. Neue Untersuchungen aus Europa und den USA zeigen, dass die Versorgung mit ß-Carotin aus dem Grundfuttermittel schlechter ist als allgemein erwartet. In diesen Fällen kann eine gezielte Ergänzung sinnvoll sein.
