Answer

Coagulation studies are needed in anticoagulated patients or in patients with known or suspected bleeding diathesis. In severe infection in which systemic sepsis is a concern, disseminated intravascular coagulation (DIC), though quite rare, must be ruled out.

Test for rheumatoid factor if rheumatoid arthritis is a consideration.

Gonococcal cultures of the urethra or cervix, rectum, and pharynx are appropriate if gonococcal tenosynovitis is suspected. One of these cultures is positive in approximately 80% of patients. In addition, transiently elevated liver function studies (LFTs) have been described with disseminated gonococcal infection.
