Determination of the erythrocyte sedimentation rate (ESR) is appropriate if an infectious etiology is suspected in tenosynovitis, though the ESR is nonspecific for the disorder. Characteristics include the following:

  • The ESR typically is elevated in acute or chronic infections and may serve as a marker to follow resolution of an infection
  • The ESR may be elevated in cases of inflammatory flexor tenosynovitis (FT) as well
  • The ESR is not elevated in nonsuppurative conditions
