Labcorp catalog pageMethod 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.
- Reference notes
- Reference intervals are established by the laboratory. See table.

Verify these ranges and sources
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.
