Calcium MTB Methylthymolblue Method

Calcium MTB Methylthymolblue Method
Calcium ions form in the presence of methylthymolblue a blue dye complex. The absorbance increase at 578 nm Hg or at 612 nm is proportional to the calcium concentration. In presence of 8-Hydroxyquinoline, magnesium ions do not interfere. The colour reagent is very stable

Intended use
vitro test for the quantitative determination of calcium in human serum, plasma and urine on automated clinical chemistry analysers.
