What is the difference between the Lactose/Galactose Assay Kit (Rapid) (K-LACGAR) and the Lactose Assay Kit - Sequential/High Sensitivity (K-LOLAC)?

K-LACGAR can quantify both lactose and galactose individually once the analytes are within the linear range of the assay. This is performed as two individual assays as outlined on page 5 of the booklet with the calculations for both outlined on page 6. If the sample is low in lactose a borohydride reduction step is required to remove high levels of monosaccharides.

K-LOLAC is best suited for samples considered low in lactose or lactose free. This measures glucose initially (remainder of glucose following GOX/CAT treatment) and then the glucose released from the breakdown of lactose. This assay includes a treatment with glucose oxidase/catalase to remove free glucose prior to lactose analysis to avoid any interference to the lactose determination.
