Resources

 

The Clinical Laboratory of University of Colorado Hospital in metro Denver is accredited by the College of American Pathologists and all relevant state and federal agencies.

Laboratory specialty activities are directed by experts in their area of clinical specialization who are available for consultation. Medical Directors of any specialty may be called directly (see “Staff Contacts”) or contacted through the Clinical Laboratory at 720-848-4401.

The Clinical Laboratory does not handle nor transport anatomical specimens. All cytology, surgical, and other anatomical specimens, and inquiry regarding these are the responsibility of the University of Colorado Denver Department of Pathology. Please go to UCD Department of Pathology and click “Our Services” for specimen submission guidelines.

Referral-Send Out Testing


Referral-Send out Testing

Certain tests are not listed in the laboratory test catalog or on the requisition forms. If the specific test is not routinely performed through the Clinical Laboratory, the laboratory will arrange for its performance at a reference laboratory. Call 720-848-7029.

The Clinical Laboratory will refer specimens to licensed/accredited referral laboratories only for test procedures not available on site. The name of the laboratory actually performing the examination will be indicated on the laboratory report form.

The UCH Clinical Laboratory has mandatory processes for selection and approval of outside reference laboratories and reference lab testing.  If any unit or clinic bypasses the Clinical Laboratory Specimen Management area to send or take a specimen to an outside laboratory directly, the hospital/outside laboratory will not pay the laboratory for the test. 

Clinicians may submit this request form for new tests to the Lab Orders Optimization Committee: Request for New Tests


Compliance

Every laboratory test must be ordered under the license of a physician or other authorized provider and must be requested using the appropriate electronic ordering system (e.g. Epic), or if an ordering system is unavailable, on the appropriate requisition form.

Note: Medicare generally does not cover routine screening tests or services when a “rule-out” diagnosis is provided. Code the condition(s) to the highest degree of certainty for that encounter/visit, such as signs, symptoms, abnormal test results, exposure to communicable disease or other reasons for the visit.

  3. The test was not ordered in the previous 24 hours.
  4. Previous result within 24 hours was not a critical value. (The patient’s result has changed from a critical value to a non-critical value, then back to a critical value.)

Positive test results considered significant, but not defined as critical will be called to the caregiver on the same day that the results are available. These results are:

  • D-dimer (Outpatients only; excludes patients in Emergency Department) ≥ 500 ng FEU/mL
  • Positive AFB smears
