Lab Test

Culture, Intrauterine Device

Actinomyces, Anaerobe, Anaerobic, IUD

Test Codes



  • Only Actinomyces spp. will be further identified from intrauterine devices.
  • Gram stains will not be performed on intrauterine devices.

Specimen Collection Criteria

 Collect: Place intrauterine device in a sterile collection container.

Physician Office/Draw Specimen Preparation

Deliver to the Laboratory in a sterile container at room temperature (20-26°C or 68-78.8°F) within 4 hours of collection.

Preparation for Courier Transport

Transport: Room temperature (20-26°C or 68-78.8°F).

Rejection Criteria

Specimens in non-sterile or leaking containers.

Inpatient Specimen Preparation

Transport all specimen types to the Laboratory immediately after collection.

In-Lab Processing

If an intrauterine device culture is ordered on an inappropriate site/source or collection device, the order will be changed to match the appropriate test code.


Specimen Stability for Testing:

Room Temperature (20-26°C or 68-78.8°F): 24 hours
Refrigerated (2-8°C or 36-46°F): Unacceptable
Frozen (-20°C/-4°F or below): Unacceptable

Specimen Storage in Department Prior to Disposal:

Refrigerated (2-8°C or 36-46°F): 7 days


Farmington Hills sent to Royal Oak Microbiology Laboratory for testing.
Grosse Pointe sent to Royal Oak Microbiology Laboratory for testing.
Royal Oak Microbiology Laboratory
Troy sent to Royal Oak Microbiology Laboratory for testing.


Sunday – Saturday, 24 hours a day.
Final negative results available within one week.

Reference Range

No organisms recovered.

Test Methodology

Anaerobic culture and identification. Anaerobic susceptibility testing must be approved by the Microbiology Director.


The recovery of Actinomyces spp. may be indicative of an infectious disease process.

Clinical Utility

This test is used to recover and identify Actinomyces spp. that may be involved in human infections. Pelvic Actinomyces israelii has been described in association with the use of intrauterine devices (IUDs).

If an IUD infection is suspected consider ordering a Vaginosis Screen or Chlamydia trachomatis and Neisseria gonorrhoeae Detection by Nucleic Acid Amplification.
