BD MiniDraw™ Capillary System Clinical Equivalence Study

The current method for collection of a large volume of capillary blood (up to 600 µL) involves optional warming of the hand or finger prior to procedure, lancing of the fingertip, squeezing the fingertip by hand, and dripping the blood into an open non-sterile tube. The capillary blood collection process is considered cumbersome and lacks standardization in how much pressure is applied in squeezing of the finger which may lead to poor sample quality or insufficient blood volume. Common sample quality issues for capillary blood collection include hemolysis and dilution of sample with interstitial fluid, potentially causing bias in test results. Open collection also carries a risk of blood exposure for healthcare workers and potential risk of infection at the finger puncture site. A new device, BD Microtainer® Easy Collect Capillary Blood Collection System for the collection of capillary blood was created to standardize the current collection process and improve sample quality. This study designed to evaluate the safety and effectiveness of the BD Microtainer® Easy Collect Capillary Tube SST™ and BD Microtainer® Easy Collect Capillary Tube EDTA devices. This study will be conducted in two parts, one for the SST product and the other for the EDTA product. A minimum of 100 participants, and a maximum of 150 participants per part will be enrolled at a minimum of three various ancillary healthcare site settings representative of the intended use environment such as retail pharmacy site, patient service center, and/or urgent care clinic. Samples will be collected by representative future users of the BD Microtainer® Easy Collect Capillary Blood Collection System who may not have prior blood collection experience. Comparator venous and conventional capillary tubes will be collected by skilled healthcare professionals with phlebotomy experience. Samples will be collected, clotted (serum samples only) and centrifuged (serum samples only) before transportation to the laboratory where they will be tested. Average differences between the investigational device compared to a marketed comparator will be evaluated. Visual observations for the SST products will be captured which include hemolysis as measured by Plasma Free Hemoglobin (PFH); collection volume; and duration of sample collection. Visual Observations for the EDTA products will be captured which include frequency of occurrence of instrument flags; frequency of occurrence of platelet clump instrument flags; frequency of instrument platelet clump flags with no platelet clump; evaluate whole blood collection volume; and duration of sample collection. Lastly, device safety will be assessed by device and procedure related adverse events.
