Estimation Of - Serum Urea In Laboratory

Sample:- Urine

Reagent:-
Reagent R1a + R1b = Working Reagent
And R2 Reagent

Procedure:-
         1000 µl Working Reagent 
                       +
            Add 10 µl Serum
                       + 
         Add 200 µl R2 Reagent
                       +
          Wait For 10 Minute
                       +
          Reading On Analyzer

Standard :- R1 1000 µl + 10 µl Standard Solution 

Note:- R2 Reagent is counter reagent, so its dont use to make Standard Solution .
