Iowa Code § 85A.11: Diagnosis for brucellosis.

1. If any employee is clinically diagnosed as having brucellosis, the employee shall not be considered to have the disease unless the clinical diagnosis is confirmed by either of the following:

a. A positive blood culture for brucella organisms.

b. A positive agglutination test which must be verified by not less than two successive positive agglutination tests, each of which tests shall be positive in a titer of one to one hundred sixty or higher. The subsequent agglutination tests must be made of specimens taken not less than seven nor more than ten days after each preceding test.

2. The specimens for the tests required by this section must be taken by a licensed practicing physician or osteopathic physician, and immediately delivered to the state hygienic laboratory. Each specimen shall be in a container upon which is plainly printed the name and address of the subject, the date when the specimen was taken, the name and address of the subject’s employer, and a certificate by the physician or osteopathic physician that the physician took the specimen from the named subject on the date stated over the physician’s signature and address.

3. The state hygienic laboratory shall immediately make the test and upon completion thereof it shall send a report of the result of such test to the physician or osteopathic physician from whom the specimen was received and also to the employer.

4. In the event of a dispute as to whether the employee has brucellosis, the matter shall be determined as any other disputed case.
