Specimen: 

Urethral or cervical
A ProbeTec ET collection kit (gender specific) is available from the Microbiology Dept.  This kit contains a cleaning swab, collection swab and transport tube for females and a collection swab and transport tube for males. The transporter must be delivered to Mercy Lab within 6 days of collection and should be transported between 2-27 degrees celcius. The same tranporter can be used for GC DNA Probe testing.

Urine
15 – 20 mL of freshly voided urine. The patient should not have urinated for at least 1h prior to specimen collection. Store urine refrigerated @ 2-6°C and deliver the urine to Mercy Lab within 7 days of collection. If the urine was stored @ room temperature before delivery, please call the Mercy Microbiology Department for further instructions (Ext. 7494).

RL: SPECIMENS RECEIVED IN PRESERVATIVE VIALS ARE NOT ACCEPTABLE FOR TESTING AND WILL BE REJECTED. See urine collection instructions below.

Cervical Specimen Collection:

Use the ProbeTec ET collection kit for females. Using the large cleaning swab provided in the kit, remove the excess mucous from the endocervix.  Discard the swab. Insert the smaller Female Endocervical Swab into the cervical canal and rotate vigorously for approximately 30 seconds.  Avoid touching the vaginal walls when withdrawing the specimen.  Place the swab into the transport tube and snap the swab off at the score mark. Tightly cap the tube and label with the patient’s name, date and time of collection. (Swab must be left in the transport tube.)  Transport at 2-27 degrees celsius, within 6 days of collection.

Urethral Specimen Collection (male):

Use the ProbeTec ET collection kit for males.  Patient should NOT have urinated one hour prior to specimen collection.  Insert a small Dacron swab 2-4 cm into the urethra.  Rotate the swab for 5 seconds and withdraw.  Place the swab in the transport tube and snap the swab off at the score mark. Tightly cap the tube and label with the patient’s name, date and time of collection. (Swab must be left in the transport tube.) Transport at 2-27 degrees celsius, within 6 days of collection.

Urine Collection:

Collect specimen in a sterile, plastic, preservative-free specimen collection cup. The patient should not urinate for at least one hour prior to collection of specimen. Patient should collect the first 15-20 mL (maximum 60 mL) of a voided urine (the first part of stream, not mid-stream). Tightly cap the urine and label with the patient’s name, date and time of collection. Store the urine in the refrigerator (2-6°C) until transport to Mercy Lab. Transport refrigerated, within 7 days of collection.

 

 

Cause for rejection:

  • Transport tubes that are received without collection swabs inside.
  • Transport tubes that have expired.
  • Transport tubes received with a swab different from the one provided in the collection kit.
  • Transporters received frozen.

Specimen collected from a site other than cervical, male urethral or urine

Comment:

  • In the case of suspected child abuse, culture is the only recommended procedure. See: Chlamydia Trachomatis Culture

 Test stool for C. difficile on all patients with clinically significant diarrhea AND history of antibiotic exposure.

 

 

Specimen:

FRESH SPECIMEN ONLY: 

Only 1 specimen per diarrheal episode is necessary for diagnosis.

2 grams of fresh stool submitted in a tight fitting lid container, refrigerated (*or frozen)

  • Refrigerated (2-80C) stools are stable for 4 days. *If delivery and or testing cannot take place within 4 days of refrigeration, the sample should be frozen at <-200C, until testing can occur.

Consider C. Difficile testing as an alternative to routine microbiologic studies for INPATIENTS that have been hospitalized for more than 3 days.

 

 Cause for Rejection:

  • Specimens collected within 24 hous of barium or bismuth enema
  • Specimens contaminated with toilet water or urine
  • Specimens are not sent frozen, if refrigeration has exceeded 4 days.

Comment: 

  • Patient should be passing 5 or more liquid or soft stool per 24 hours to be tested for Clostridium difficile. 
  • Formed stools are not indicative of Clostridium difficile associated disease, and will not be tested
  •  Not to be used for children
  • Not to be used as a "test of cure," as this test will also detect non-viable organisms that persist after treatment.
  • Useful as an aid in diagnosis of antibiotic associated pseudomembraneous colitis.
  • Collect samples at least 24 hours post barium or bismuth enema.

RL Comments:

  • Mark CLOSTRIDIUM DIFFICILE on the order form.
  • Fresh stool should be refrigerated immediately. Send stool refrigerated. A refrigerated stool is stable for 4 days. If delivery or testing will exceed 4 days, the stool should be frozen at <-200C, and sent frozen
