Exercise 32

Synovial fluid for crystal examination should be examined as a/an:

A. Wet preparation

B. Wright's stain

C. Gram stain

D. Acid-fast stain

Step 1 of 2

Crystal examination:

The crystal examination in fluid should be performed immediately to prevent change in temperate and pH.

• If the synovial fluid is refrigerated before testing, then temperate of the fluid will be changed; this action affects crystals in the collected fluids.

• Most importantly the synovial fluid should be examined as an unstained wet preparation.

o Because, a drop of fluid is placed on a pre-cleaned glass slide and cover slip is placed on it for examination.

o For this examination the fluid is required to be wet prepared and unstained for accurate result.

Therefore, synovial fluid for crystal examination must be examined as a “wet preparation”. Hence, the correct answer is option .
