On May 1, 2017, Spectrum Health Regional Laboratory adjusted the reference range for C-Reactive Protein (CRP) from ≤10 mg/L to ≤5.0 mg/L.
The following tests are now available:
Tree Nut Component Allergens
In addition to allergen components for egg, milk, and peanut, the test menu at Spectrum Health Regional Laboratory has expanded to offer component testing for tree nuts. Component testing measures sIgE antibodies to individual proteins unlike whole allergen testing which measures the presence of specific immunoglobulin E (sIgE) antibodies to a combination of allergenic and non-allergenic proteins. This next generation testing identifies the source of sensitization and helps the clinician assess the risk of systemic reaction.
As of January 12, 2016, pathologist review of peripheral blood smear ordered without accompanying CBC with differential will reflex to adding on a CBC and/or differential in the laboratory. Blood specimens that do not have a slide prepared need to be less than 6 hours old for a pathologist review to be added on.
This is due to the fact that older blood does not smear well and morphology is compromised, especially red cell morphology. This allows for a complete documentation of the patient’s CBC and differential findings in the electronic medical record and standardizes our process among the regional hospitals.
Any questions concerning Peripheral Blood Smear reflexes should be directed to Dr. Jennifer Stumph, Director of Hematology.
We are currently evaluating serum Thyroglobulin Tumor Marker test ordering practices as the volume has quadrupled over the last 3 years without a quadrupling of total laboratory volume.
If you order this test, please contact Dr. David Alter with the reason for ordering the test.
Of note, the only stated reason in “UPTODATE” is monitoring for recurrence of medullary thyroid cancer status post treatment.
- Monitoring treatment
- Serum thyroglobulin as a marker for autoimmune thyroiditis
- Serum thyroglobulin ordered for the accompanying anti-thyroglobulin antibody result
- Other, please elaborate.
