A. Total protein

B. Uric acid

C. Calcium

D. Glucose

Step 1 of 2

Synovial fluid:

Synovial or movable joints have a hollow space filled with viscous fluid termed as synovial or joint fluid.

• The cavity containing synovial fluid separates the bones present in synovial joints which are lined with smoother articular cartilage.

Chemical test on synovial fluid:

The synovial fluid is an ultra-filtrate of plasma; the values of chemical tests achieved on synovial fluid are same as values of serum.

• Therefore, few chemical tests are considered as clinically most significant.

• The most often requested test in synovial fluid is “glucose” determination.

o Because reduction of glucose values in synovial fluid indicates inflammatory or septic disorder.

o Normal synovial fluid glucose values are based on blood glucose volume.

Therefore, the most frequently executed chemical test on synovial fluid is “glucose”. Hence, the correct answer is option “”.
