Answer to Question 1

A

Answer to Question 2

A
Feedback:
A single-voided urine specimen often is ordered. Tests are done to determine the efficiency of the kidneys or to examine the urine for abnormalities. By using the clean-catch or midstream method, a specimen is obtained with minimal contamination from external sources without inserting a sterile catheter. An accumulated quantity of urine gives more detailed information than does a single specimen because the accumulated specimen better shows the type and quantity of wastes being excreted by the kidneys. The urine is usually collected for 24 hours or for some part of that period, depending on the specific order.
