Exercise 44

Performing a clearance test using radionucleotides:

A. Eliminates the need to collect urine

B. Does not require an infusion

C. Provides visualization of the filtration

D. Both A and C

Step 1 of 2

Clearance test using radio nucleotides:

The radio isotopes are used to give the kidney functions.

• T_c99 m-MAG3 (mercaptoacetyltriglycine) and T_c99 m-DTPA (diethylene-triamine-pentaacetate) pharmaceutical agents used for clearance test using radio isotopes.

• The agents are injected into the body by venous system.

• The kidney excretes this compound in urine.

• This process can be viewed with gamma camera.

• Kidney filtration activity will be analyzed with this technique.

• It is widely used before the kidney transplantation process.

• It does not need collection of urine samples and visualization of filtration is possible by “gamma camera”.

Therefore, usage of radio nucleotides in clearance test “eliminates the need to collect urine”, and “provide the visualization of filtration”. Hence, the correct answer is option .
