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.

Why 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.

  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.

pdf Ordering test kits
  • You can order quantities of 50, 100, or specify the number you need.
  • The collection tubes have expiration dates, so order no more than the number of kits you will use in a 3-month period.
  • The cost of the kits is included in the testing fee, so you pay nothing.
  • It will take up to 10 days for you to receive your kits.

pdf Sample collection instructions
  • Tests should be done at your office. If a test is done at a patient's home, contaminants could get into the sample container requiring retesting due to indeterminate results. Or too large a volume (only 20 - 30 ml is needed) could be collected, diluting the sample and decreasing sensitivity.
  • Urine samples don't require a clean catch; however, your patient must not urinate for 60 minutes prior to collection.
Print out the detailed instructions for collecting the samples.

pdf Sending samples to the lab
  • Samples have a 30-day limit. They may be refrigerated.
  • Samples may be mailed (cost of about $2 to mail 5 vials in one package), dropped off, or sent by courier.
  • Samples sent by mail require USPS-approved packaging, which is included in the urine test kits.
  • If you use a courier, triple packaging is not required. Samples may be sent in a biohazard-safe container.
  • Results will be faxed to your office in 24-48 hours if you have requested this service (see step 1) or by mail in 3-5 days.

To order, send a completed requisition form (below) to your health department's regional laboratory.

Check the regional laboratory directory on the www.michigan.gov website for the health department serving your office.


Billing for tests
Use either CPT 87491 or 87810. If you bill both, they will cancel each other out.

Following up after testing
  • You'll get results by fax in 24-48 hours, 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. According to the CDC, retesting should be encouraged for women three to four months after treatment.
  • The CDC recommends retesting women 3 to 4 months after treatment.
