The Holst milt test for diagnosing AFB can be found many places on the Internet. http://www.oie.int/eng/normes/MMANUAL/A_00105.htm for instance. All references refer to a 1% solution of dried skim milk, but nowhere can I find exactly what that means or how to mix a 1% solution of dried skip milk. Is that a solution of 1% dried skim milk or is it a 1% solution of reconstituted skim milk (which would be a very dilute solution). Can anyone set me straight?
