These single-use test kits are easy to use and very accurate. The technology is very similar to some of the home pregnancy test kits. Complete instructions included. This kit tests for American Foulbrood. If you have some brood that looks diseased, and both of this test and the EFB Test are negative, you should consider chalkbrood, sacbrood, other viruses, and varroa mites causing Parasitic Mite Syndrome. Remember to report any positive results to your veterinarian or state apiculturist. They may be able to help you manage the disease.
