Topical tetracycline solution is an alternative to the burrow ink test. After application and removal of the excess tetracycline solution with alcohol, the burrow is examined under a Wood light. The remaining tetracycline within the burrow fluoresces a greenish color. This method is preferred because tetracycline is a colorless solution and large areas of skin can be examined.
