The plate can be measured without further incubation. Fluorescence intensity directly reflects albumin concentration. Specimen and Sample Storage Random urine is the simplest approach to obtaining a specimen for analysis, but gives the most variable results. The preferred specimen is 24-hr urine without preservative. The albumin measurement is multiplied by the volume expressed in L to obtain mg albumin excreted in 24 hr.
Refrigerated samples are stable for up to two weeks.
Preparation Warm up kit to room temperature. Test Procedure 1. Mix well, e.g. by suspending with an 8-channel multipipette or by mixing in a microplate mixer. Limitations With hemolytic specimen slightly lower relative fluorescence counts may be found. This test is intended for measuring microalbuminuria only.
