Urea:
sample is serum or plasma.
Procedure :
1.prepare two test tubes mark one as test tube and the other is standard tube .
2.in standard tube put : 1 ml buffer + one drop urease (R2) + 10 µ standard reagent (R1) leave for 5 min. in room temp.
3.in test tube put at same time : 1 ml buffer + one drop urease (R2) +
10 µ serum or plasma then leave for 5 min in room temp.
4.then put 200 µ of Reagent 4 (R4) and leave for 5 min. in water bath or 10 min. in room temp.
5.Measure at 580 wave length.
Calculation :
[ reading test / reading standard ] x 50 =.......mg / dl . OR [ reading test / reading standard ] x 8.33 =......mmol /l
Normal values:
15 - 45 mg / dl.
