Services Which Are Not Offered Or Require Laboratory Staff Approval

Certain requests for laboratory testing require the express approval of the professional staff of the Clinical Laboratories, which will be governed by the following guidelines:

  1. Stat testing:
    Stat performance of tests other than assays designated as available 'stat' in Apex or listed on the (pink) Emergency requisition requires review and approval; to obtain such approval, call the laboratory at 3-1667.

    The overriding determinants are (1) if the test can actually be performed stat and (2) whether the test will genuinely contribute to the clinical management of the patient, and that management will promptly be altered by the test result. Otherwise the test should be delayed to a more convenient and/or less expensive time. If the result is clinically important, every reasonable effort will be made to arrange for the test to be run stat. The ease or expense of performing the test stat should be considered only after it is decided that the test will be useful.

  2. "Not offered" (Obsolete or Otherwise Inadequate Assays):
    This statement in the Laboratory Manual reflects the decision of the laboratory staff that the test should not be provided because of obsolescence, lack of demonstrated utility and/or because of technical or biological inadequacies. Such tests will only be referred to be performed with the agreement of a laboratory section chief or the laboratory Director.

  3. "Requires Approval":
    The staff, laboratory resident or director of the laboratory section which performs the test - or which has the expertise regarding a test performed by an outside reference laboratory - will review the request.

  4. Tests Not Listed in the Laboratory Manual:
    Tests may not be listed at all because they are rarely requested or because they are very new; in the latter case sufficient information may not yet be available to evaluate the test and it may be regarded as experimental. Referral of such tests requires approval as outlined above. If the utility of a test has not been demonstrated to the satisfaction of the laboratory staff, the ordering physician will be asked to support a request with references, etc. If an uncommon test is clearly useful, we will make every reasonable effort to identify an appropriate source of testing by a CLIA certified and licensed clinical laboratory, forward the specimen and arrange for payment. If you would like a test to be added to the laboratory manual, please complete and submit the request at: New Test Request.

  5. Automatic Review of Potentially Inappropriate Tests:
    Certain test requests will be reviewed because of the empirical observation that physicians ordering them frequently need assistance in obtaining optimal laboratory evaluation of the clinical problem. E.g., viral serologic tests are frequently ordered incorrectly, the same test sometimes being requested on multiple occasions within a few days; e.g. additional information cannot be obtained from a second EBV titer in someone evidencing past infection in the first specimen submitted, or from a varicella-zoster antibody titer in a patient who has just received zoster immune globulin.

  6. Send-out Research tests:
    The clinical laboratories are not staffed to send research samples to other institutions. Supplies, packaging, and shipment of such samples is not an offered service.

  7. Referral of Clinical Samples to an Unlicensed Laboratory:
    Federal CLIA '88 regulations forbid the referral of patient samples for testing to a non-CLIA certified laboratory. Requests to send samples to non-certified facilities (foreign or research labs) will be denied.

  8. Referral of Tests on a Medi-Cal Patient to a Laboratory that does not have a Medi-Cal provider number:
    Medi-Cal will only reimburse the expense of laboratory testing if the laboratory is licensed by the state of California and has a valid Medi-Cal provider number; out-of-state laboratories, in particular, are often unwilling to undertake the California licensing and Medi-Cal provider application. However, Medi-Cal-enrolled children with certain medical conditions are eligible for California Children's Services (CCS) coverage, which may reimburse a non-Medi-Cal laboratory. For information concerning a pediatric patient's eligibility or enrollment in CCS and CCS's willingness to reimburse the non-Medi-Cal laboratory, contact the regional CCS administrator (presently Marguerite Taylor) at (415) 904-9682.

    Assuming that the non-Medi-Cal laboratory holds a valid license (if required) in the state where it is located and is federally licensed under the Clinical Laboratories Improvement Act, CCS reimbursement may be approved. All other Medi-Cal patients must prepay in cash for the test desired and all related shipping costs, or payment must be arranged from non-patient funds.

 

Abbreviations Used In Test Tables & Result Reports

Note: The minimum volumes given in the tables are generally sufficient for a single assay and do not permit repeating the assay to check an unusual result, for sampling error or some other technical problem.
