Exercise 6

Failure to mix a specimen before inserting the reagent strip will primarily affect the:

A. Glucose reading

B. Blood reading

C. Leukocyte reading

D. Both B and C

Step 1 of 2

Reagent strip technique:

The specimen in which the reagent has to be dipped is thoroughly mixed.

• The reagent strip is dipped into the specimen.

• The strip is taken out from the specimen carefully.

• Horizontally the strip is blotted on absorbent material.

• Comparing the obtained color in strip with the manufacturers chart.

• The specimen if not mixed well, for example if an unmixed specimen is tested, the leukocyte and erythrocyte (blood cells) reading are affected.

• The leukocyte and erythrocyte gets settles at the bottom container and cannot be identified in the reagent strip.

Therefore, the “blood reading” and “leukocyte reading” are affected in case of failure to mix the specimen prior to the insertion of reagent. Hence, the correct answer is option .
