Objective:To evaluate the determination of total protein in cerebrospinal fluid and urine using BECKMAN CX
3
DELTA.Methods:The improved biuret method of BECKMAN CX
3
DELTA in determining total protein in urine and cerebrospinal fluid
was compared with sulfosalicylic acid method in OLYMPUS AU-560.Results:The result of total protein in cerebrospinal fluid determined with these two methods was (±s)303.85±80.44mg/L and 297.31±79.43mg/L respectively
showing no significant difference between them(P
>
0.05).As to the urine whether it is from the normal group or the patient group
there was always significant difference between two methods(P
<
0.01)
and vitamin C and uric acid both added positive distraction to the results.The addition of 30% H

could help to clear off the distraction
but not satisfactorily.Conclusion:BECKMAN CX
3
DELTA can determine the total protein in cerebrospinal fluid quickly and accurately.While as urine is complex
errors always occur in the determination
it is not suitable.
