Urinalysis and Body Fluids 6th Edition by Majorie DiLorenzo, Susan Strasinger

Exercise 7

The medical technologist was assigned to test 10 urine specimens chemically. She removed 10 strips from the container and proceeded with testing. Several patients’ urine indicated a trace positive glucose in the urine.She then opened a new bottle of reagent dipsticks and proceeded to perform the QC. The negative control also tested as a race positive for glucose. The medical technologist consulted the supervisor. The supervisor ran the QC and the results were in the correct range.After observing the medical technologist’s technique,the supervisor realized that the medical technologist was waiting too long to read the glucose results and therefore reporting erroneous results.

a. What is wrong with this scenario?

b. Who should run the QC for each test? Why?

c. When should controls be run?

d. What do you do when the QC is out of range?

e. When can you report patient results?

Step 1 of 5

a.

Wrong in this scenario

• The medical technologist waited for much time to read glucose results

• This procedure is incorrect

• Proper timing of glucose reaction was not performed
