Anniston Community Health Survey: Follow up Study and Dioxin Analyses

Clinical Test Results Report

Dear Participant,

The following tables show the results of clinical tests that we performed in your blood or serum on mm/dd/yyyy. The results that are out of normal range are marked red.

These clinical tests are mostly those that your doctor would perform in an office. We would advise you to go over the results with your doctor. If he or she has any questions about some of the more specialized tests we did, he/she can contact us at numbers provided below.

Because we are providing these results ______ months after your blood was collected, the results may be of limited value to you or your physician, especially if you are already under treatment or being followed for a particular chronic condition that the results indicate.

Some individuals will not have the measurements for all tests. You may not have a measurement for some test because your level is lower than the limit of detection. You may also not have a measurement because your blood sample failed one of the laboratory quality control procedures. If the reason for missing measurement is known, that reason will be included with your results.

You or your physician may contact us with questions about your clinical test results by calling ATSDR at 770-488-____.

Thank you for your understanding and your participation in the study.

Sincerely,

Study investigators.
