Basophil activation test with indomethacin to assess hypersensitivity to non-steroidal anti-inflammatory drugs: a preliminary study.

Background: The basophil activation test has been investigated for diagnosing hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs). This has not yet been done in relation to indomethacin.

Objective: First seek to establish the viable concentrations of indomethacin and the diluent propylene glycol (PPG) in relation to basophils then test this in patients with hypersensitivity to NSAIDs.
