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

Exercise 4

A patient collecting a midstream clean-catch specimen voids immediately into the container.

a. How could this affect the clarity of the specimen?

b. How could this affect the microscopic examination?

Step 1 of 2

a.

Mid-stream clean catch specimen:

In the mid way of urination, urine is collected.

• It is a safer specimen

• The specimen collected in mid-stream clean catch is used in routine analysis of urine and bacterial culture

• The specimen is collected by the patient

Therefore, the specimen collected instantaneously after voiding provides less clear specimen.
