Abstract
We evaluated whole blood samples drawn from 25 healthy donors and 20 HIV-infected donors into K3EDTA and Cyto-Chex BCT blood collection tubes for CD4, CD8, and CD3 cell counts (HIV Panel). Samples collected in Cyto-Chex BCT were stored at room temperature and tested by 4-color flow cytometry at 6 h, 3 days, and 7 days after isolation for CD4, CD8, and CD3 absolute cell counts/microl and compared with samples collected in K3EDTA tubes and tested at 6 h. Regardless of donor type, the samples collected in Cyto-Chex BCT and tested on day 7 yielded results that were statistically indistinguishable (with correlation coefficients of 0.96 or greater) from samples collected in K3EDTA tubes and tested at 6 h. We conclude that whole blood samples collected in Cyto-Chex BCT are stabilized for their marker phenotype for at least 7 days after phlebotomy.Entities:
