Abstract
Counterimmunoelectrophoresis used for the diagnosis of mycetoma was found superior to immunodiffusion (ID) especially when using neat serum and 1:2 dilution (P = <0·0001 with neat serum; and <0·01 with 1:2 dilution). It is recommended for routine use in mycology laboratories for following up patients on treatment and for confirming the diagnosis of sera that are weakly positive by ID.
