Reminder: Winter Lock Box

march-winter-lockboxTo maintain optimal specimen integrity, Spectrum Health Laboratory requests that you load your outdoor lock box properly for winter weather temperatures. Please follow the diagram on the right to prevent freezing of specimens.

Frozen specimen should never be left in the lock box for after-hours pickup. These tests may be better preserved in the office freezer until the next day’s courier pickup.

Request for specimen pickup should be made to the Laboratory Call Center at 616.774.7721.

Supplies may be ordered using the Supply Order Form.

Test Update: Cystatin C

Effective Wednesday, December 18, 2019, Cystatin C will change from a sendout reference test performed by Mayo Clinic Laboratories to an in-house test performed by Spectrum Health Regional Laboratory. This test will be performed in the Toxicology Laboratory and will include a new reference range (please see link in Test Information below).

Questions may be directed to Toxicology via the “contact us” link above.

TEST INFORMATION

Cystatin C – Epic Code #LAB3226, Interface #11631, CPT #82610

Appropriate Thyroid Peroxidase Antibody Ordering

The most conclusive evidence for using thyroid peroxidase antibody (TPO) is predictive in nature when evaluating possible subclinical hypothyroidism. If this test is positive, hypothyroidism occurs at a rate of 4.3% per year versus 2.6% per year when the antibody is negative. While this scenario does not cover all clinical indications for ordering TPO, there is no definitive evidence that repeat TPO testing provides additional information.1

Based on this information the ordering of TPO within Spectrum Health is being modified. If the test is ordered more than once on a patient, a screen will appear in EPIC indicating the following: “This test should typically only be resulted once per lifetime. The duplicate checking indicates that this patient has already had this testing performed. Please see chart review for results.” This is not a “hard stop” but providers will need to click “Continue” to proceed with the order. Continue Reading

Protein Electrophoresis Testing Update

In December, serum and urine protein electrophoresis testing will be simplified and standardized.  The only testing available will be:

Protein electrophoresis, serum, IFE if indicated 

Protein electrophoresis, random urine, do IFE if indicated 

Protein electrophoresis, 24 hour urine, do IFE if indicated 

In addition, on December 5, 2019, a new panel will be added which reflects expert recommendations for first line testing for monoclonal gammopathy, including plasma cell myeloma and most cases of amyloidosis, called “Monoclonal Gammopathy Screen

Protein electrophoresis, serum, IFE if indicated 

Kappa and lambda free light chains  Continue Reading
