    (c) Identification. Any captive cervid tested with an official 
tuberculosis test must bear official identification in the form of an 
official eartag, or another identification device or method approved by 
the Administrator as unique and traceable, at the time of the official

State and Federal animal health officials of the State in which the 
captive cervid is tested. The report must include the following 
information for all SCT and CCT tests administered: The number of the 
individual eartag or other identification approved by the Administrator; 
the age, sex, and breed of each captive cervid tested; a record of all 
responses; the size of each response for the CCT test; and the test 
interpretation.
    (2) BTB test. Copies of the BTB test results must be submitted by 
the testing laboratory to the person, firm, or corporation responsible 
for the management of the herd, cooperating State and Federal animal 
health officials of the State in which the captive cervid is tested, and 
the testing veterinarian. The report must include the following 
information for all BTB tests administered: The number of the individual 
eartag or other identification approved by the Administrator; the age, 
sex, and breed of each captive cervid tested; the test interpretation, 
and a summary of supporting data. Full supporting data must be submitted 
by the testing laboratory on a case-by-case basis at the request of 
cooperating State and Federal animal health officials.
    (e) Test interpretation.(1) Interpretation of an SCT test will be 
based upon the judgment of the testing veterinarian after observation 
and palpation of the injection site, in accordance with the
