(1) Capability for test depends upon lab inventory. Tests cannot be performed without required analytical standard, reagents, or solvents for specified test. Inquire prior to sample submission.

(2) If not USP method or other referenced pharmacopeia, only AHF approved or verified testing methods may be performed.
NOTE: Residual Solvents (USP<467>) currently not being tested as sampling instrumentation has not been qualified as of date of this compiled list.
