Due to the nationwide shortage of Citrate plasma collection tubes (light blue tops), please refer to the pediatric minimum samples listed on our website. This will allow you to draw fewer tubes and still complete testing. Please contact Client Services for possible alternate sample acceptability, 800-245-3117, option 1.
