Effective September 28th, 2020, a new generation of the serum kappa/lambda free light chain assay has been implemented.
With the implementation of the new generation of the assay there is an approximately 20% negative bias for kappa free light chains in serum containing >20 mg/dL kappa free light chain. This may affect the trending for patient who are serially monitored by this assay.
Leaky specimen containers may cause compromised test results and it is also a hazard to lab couriers and registration personnel. Leaky specimen containers are not acceptable and may be rejected.
In order to prevent leaky containers, please be sure to:
Pay close attention to the lid, making sure the screw-cap lids are fastened evenly and securely, with the threads aligned. If a patient has challenges with tightening the lid, please have them notify lab staff when they return to drop off their container.
Containers should be upright at all times, with lid on the top during transport. If container is placed in a biohazard bag, please maintain in the upright position by gripping the cup or the handle and not by the top of the bag.
The Laboratory provides a brochure “Laboratory Specimen Home Collection” for patient collection instructions. Internal offices (i.e. SHMG) may order these from Document Services using the order number X17776 (X19611 for the Spanish version). External offices may order these from Laboratory Courier Services using the Supply Order Form.

To 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.
Laboratory retention has been updated for the following tests. Laboratory retention outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded.
Effective Thursday, October 24, 2019, Pap Test orderable will be updated to meet current ASCCP criteria
In both the inpatient and outpatient settings, the laboratory has supplied 24 hour urine containers with preservative such as acetic acid, sodium hydroxide, and boric acid. Upon review of specimen stability requirements, it has been determined that a preservative is not needed prior to collection of most 24 hour urine tests as long as the 24 hour container is kept refrigerated or on ice during the collection period.
Spectrum Health has been informed by Roche Diagnostics that the proprietary reagents used to calibrate our instruments and determine control values for ferritin blood level have been updated to reflect deviation of results leading to low result bias. This may have led to patient results being up to 20% lower than actual ferritin level.
