Another great question from Kim Kinney at Clarian:
Hi again George. I have an observation that I am wondering if anyone else has noticed. We use full-draw, BD glass tubes for all of coagulation, but we have had the 1.8 mL pediatric tube come in from Riley Children’s Hospital for PT/PTT. We always check for a clot before spinning. We often get a warning on a normal PT (say, 11.0 s) on these 1.8 mL tubes indicating the fib level may be low. When we re-check the tube for clots, we then pull out a visible clot.
Could these tubes be activated due to, for example, a difficult stick and the process of spinning causes the visible clots to form? It has only happened as far as I know in the 1.8 mL tubes–just curious!
Hi, Kim. Thank you for the question. I have no experience with the 1.8 mL tubes and will post this for our participants with experience to respond. Geo
