Appropriate Labeling of Specimens

Safety of our patient and quality of care are of utmost importance. For this reason we require specimens sent to the Spectrum Health Cytology Laboratory be labeled with at least two patient identifiers, (i.e., patient legal name, birth date and MRN.) We will no longer return to the collection site, unlabeled, mislabeled specimens lacking two patient identifiers or specimen containers with multiple different patient labels. These specimens will be discarded and repeat collection will be necessary.

Procedures to verify correct labeling of patient specimens at the time of collection are recommended.   Specimen containers should not be pre-labeled. Variation of the “time-out” procedure used in the hospital and surgical center setting is an excellent way of confirming that the specimen is correctly labeled. This can easily be achieved by having the patient verify his or her name and birth date, by reading the label placed on the specimen container at the time the specimen is collected. This “time out” should occur before the specimen leaves the examination or treatment room.

It is our mission to provide the best and safest care we can to our patients. We know that physicians and other practitioners are required to see patients more efficiently and at times with less than adequate time allowed. Following a “time out” procedure and not pre-labeling specimen containers will prevent errors that may lead to diagnoses being assigned to wrong patients, hence, unnecessary procedures and lack of follow-up for the appropriate patient.

Education & Training

Zero Tolerance Specimen Labeling

All specimens submitted to Corewell Health Laboratory for testing must be appropriately labeled to assure positive identification and optimum integrity of specimens. In accordance with standards issued by The Joint Commission, at least 2 patient identifiers should be used when providing care or treatment of services (National Patient Safety Goal, NSPG.01.01.01). If 2 patient identifiers are not used on the specimen, the specimen will be rejected, the order will be cancelled and a request for recollection will be made. This includes Gyn Cytology (i.e. Pap) specimens.

What are acceptable Patient Identifiers?

  • Patient Full Legal Name
  • Date of Birth
  • Spectrum Health Medical Record Number (MRN)

Summer Lockbox Preparation

Follow these steps for loading your outdoor lockbox during the summer months to prevent overheating of refrigerated and ambient specimens:lockbox summer

1. Place a frozen cool pack in the bottom of the lockbox.

2. Layer 3 – 4 paper towels over the cool pack for insulation.

3. Place refrigerated temperature specimens on top of the paper towels.

4. Layer 3 – 4 paper towels over the refrigerated specimens for insulation.

5. Place ambient temperature specimens on top of the paper towels.

Frozen specimen should not be left in the lockbox for after-hours pickup. These tests may be better preserved in the office freezer until the next day’s courier pickup.

Corewell Health Laboratory is committed to specimen integrity. The specimen transport integrity guide is available in the online test catalog. If you have further questions please contact Laboratory Services.

Test Utilization

Ammonia, NH3

As of March 1, 2016, Corewell Health Laboratory, Grand Rapids, will no longer draw or send a courier for outpatient Ammonia testing (#8074). If outpatient Ammonia testing is needed, the patient must be collected at the 35 Michigan Draw Site. If outpatient Ammonia testing is needed and the patient cannot be drawn at the 35 Michigan Draw Site, approval must be obtained from Dr. David Alter or the Clinical Pathologist on-call, prior to ordering the test.

There will be no changes to inpatient collection. Note: Inpatients are patients who have been admitted to a hospital in the Medical Center (HDVCH, Butterworth, and Meijer Heart Center) or Blodgett Hospital.

Any questions concerning these changes may be directed to the Pathology Department using the Contact Us link above.

General Information

Reminder: Fasting Tests

Several tests performed by Corewell Health Laboratories and our Reference Laboratories (Mayo Medical Lab; Quest Diagnostics) require and recommend fasting.

Please check the Lab Test Directory prior to sending your patient to a draw site or sending a patient’s specimens to the lab. Help remind patients to arrive fasting if fasting tests are required.

Corewell Health Laboratories recommends

No caloric or caffeine intake for 8-12 hours prior to testing. Do not eat or drink anything except normal amounts of plain water. This also includes no smoking, chewing gum, candy, cough drops, etc. Some tests also require no alcoholic beverages for 24-48 hours prior to testing.

Take normal dosages of medications, unless the provider has instructed otherwise.

Results may be inaccurate if fasting was not done prior to the test and may lead to improper diagnosis or treatment. Testing will need to be repeated if patient was not fasting properly before testing.
