Chlamydia urine testing

Teens and young adults ages 16 - 25 who are sexually active should regularly be screened for chlamydia using a urine test. Studies show that more than 50% of young people have one of the 25 types of sexually transmitted infection (STIs). The most common is Chlamydiatrachomatis. Between 70% and 90% of women who are infected have no symptoms.

Follow up after chlamydia testing

You'll get results by fax in 24-48 hours (see set-up instructions, below), or by mail in 3-5 days.

Most health departments will follow up with patients who test positive for chlamydia. However, Michigan guidelines don't require it. Check with your local health department for its STI policies on follow-up and partner notification.

If a test is positive, wait at least four weeks after antimicrobial therapy is complete to do a follow-up test. Non-culture tests, like GenProbe APTIMA, should not be performed before four weeks because the presence of nonviable organisms may produce false-positive results.

The CDC recommends retesting women 3 to 4 months after treatment.

Set your office up to receive test results by fax

  • You'll get the results more quickly and won't have to schedule an unwilling teen for a Pap test.
  • If a chlamydia test is positive, a report is filed with the state automatically.
  • The patient is guaranteed confidentiality, since health departments are bound by federal HIPAA regulations and Priority Health billing information to members is generic and does not list the chlamydia test.

If your fax is down for repairs

  1. Notify MDCH immediately.
  2. If an alternate secure fax number is available, MDCH can change reporting to the alternate number. Otherwise, reports will be mailed until your machine is repaired.
  3. Notify MDCH when your secure fax number is working again.

Converting to receive test results by fax

  1. You will need a dedicated fax line at your office available 24 hours a day, 7 days a week. A dual-use phone-fax line is not acceptable.
  2. Complete the Statement of Understanding, below, and write a letter on your office letterhead requesting to become an automatic fax agency. The letter must be signed by a person authorized to make this request.
  3. Mail both the statement and letter to the Michigan Department of Community Health, Bureau of Laboratories, Data & Specimen Handling Unit - Quality Assurance Section, 3350 Martin Luther King, Jr. Blvd., Lansing, MI 48909.
  4. Reports will be faxed at 7:30 a.m., 10:30 a.m., 12:30 p.m., 2 p.m., 4:30 p.m. and 6:45 p.m. Results of blood lead, environmental lead, and newborn screening tests will not be delivered by fax.
