Mnemonic: MA DTEST

Methodology: Disk Diffusion
Performed: Sun-Sat
Reported: 1-2 days
Specimen Required: Collect: Actively growing Staphylococcus species or beta-hemolytic Streptococcus species in pure culture.

Specimen Preparation: Transport sealed container with pure culture. Place each specimen in an individually sealed bag.

By report
Interpretive Data: D-Test Positive: This isolate is presumed to be resistant to clindamycin based on the detection of inducible clindamycin resistance.  Clindamycin may still be effective in some patients.

D-Test Negative: This isolate does not demonstrate inducible clindamycin resistance in vitro.
Note: An additional handling fee will be billed for all organisms submitted that are not in pure culture as indicated in the specimen requirements.
