  2. Prepare standards by serially diluting 200 mg/l standard 1:1 to make 100, 50, 25, 12.5, 6.25 standards.

    Prepare standards by serially diluting 200 mg/l standard 1:1 to make 100, 50, 25, 12.5, 6.25 standards.

  3. Add 25 μl of standard and sample to each well.

质量控制与输出

标准曲线用二阶多项式拟合;加样避免气泡干扰荧光读数;结果需以同批标准曲线插值。

输出为每样品尿白蛋白浓度(mg/l),按标准曲线插值报告;该读数本身不是白蛋白/肌酐比值,换算比值需另测尿肌酐。
