    Method and collection
    Method
    Flow cytometry
    Collection
    Immediately invert the tube eight to 10 times after collection. To maintain cellular viability, collect the specimen in either a yellow-top tube (ACD-A or ACD-B) for arrival at the laboratory within 48 hours of collection, or a lavender-top (EDTA) tube for arrival at the laboratory within 24 hours of collection. Record the date and time of venipuncture on both the tube(s) and the test requisition form.

  • COVID-19 Triage Profile 164052

    20 analytes · Serum · Fasting not stated · Turnaround 1 - 2 days

    Method and collection
    Method
    See individual test components.
    Collection
    Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. Evacuated collection tubes must be filled to completion to ensure a proper blood to anticoagulant ratio. The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood. A discard tube is not required prior to collection of coagulation samples. When noncitrate tubes are collected for other tests, collect sterile and nonadditive (red-top) tubes prior to citrate (blue-top) tubes. Any tube containing an alternate anticoagulant should be collected after the blue-top tube. Gel-barrier tubes and serum tubes with clot initiators should also be collected after the citrate tubes. Centrifuge and carefully remove the plasma using a plastic transfer pipette, being careful not to disturb the cells.Transfer the plasma into a Labcorp PP transpak frozen purple tube with screw cap (Labcorp No. 49482). Freeze plasma within four hours of blood collection and maintain frozen until tested. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit seperate frozen specimens for each test requested.

Panels that include this biomarker

  • White Blood Cell Count (WBC) and Differential 7064

    5 analytes · Blood · Fasting not stated · Turnaround Set up: Daily (Day shift and Night shift); Report available: 2 days

    Method and collection
    Method
    Electronic Cell Sizing/Counting/Cytometry/Microscopy
    Collection
    Maintain specimen at room temperature. Do not refrigerate. If multiple draw, collect EDTA (lavender-top) tube last. Mix by gently inverting 8 times. Traumatic draw can introduce thromboplastin and trap WBC and platelets. Refrigeration can precipitate fibrin and trap WBC and platelets. Note: If drawn with lead testing, EDTA (tan-top) is required.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
