When tested with a urine reagent strip Normal urine has?

The expected range for normal urine with this test is 0.2-1.0 mg/dL (3.5-17 µmol/L). 3 A result of more than 1.0 mg/dL (17 µmol/L) should be examined further.

What reagent strip indicates bacteria in the urine?

A positive test for leukocyte esterase normally indicates the presence of bacteria and a positive nitrite test (although it is not always the case).

What is responsible for the pink positive color in the reagent strip for urobilinogen determination?

The urobilinogen test is based on the Ehrlich reaction in which diethylaminobenzaldehyde reacts with urobilinogen in acid medium to produce a pink color. Sulfonamides may produce false-positive results, and degradation of urobilinogen to urobilin may yield false-negative results.

How long should you wait before reading the results in a reagent strip in glucose?

Glucose concentrations as low as 100 mg/dL, read at either 10 or 30 seconds, may be considered abnormal if results are consistent. At 10 seconds, results should be interpreted qualitatively. For semi-quantitative results, read at 30 seconds only.

What does a reagent strip test for?

Diagnostic reagent strips are commonly used in clinical analysis of urine and blood, in particular for monitoring glucose concentration. Results are obtained instrumentally or visually as thresholds and quantitative outputs. Dry reagents are applied in the construction of strips in a variety of ways.

What does it mean when you test positive for Leukocytes and negative for nitrite?

If Leukocytes test is positive and Nitrite test is positive: results suggest UTI. If Leukocytes test is positive but Nitrite test is negative: results suggest UTI, repeat test, if Leukocytes still positive, consult healthcare provider.

Is it normal to have urobilinogen in urine?

Normal urine contains some urobilinogen. If there is little or no urobilinogen in urine, it can mean your liver isn’t working correctly. Too much urobilinogen in urine can indicate a liver disease such as hepatitis or cirrhosis.
