Etching. You can create a one-of-a-kind driveway with a technique known as etching. Patterns and designs are etched into your existing driveway with special tools to create a permanent design. The choice of designs includes stone patterns, special logos and graphics.
Depending on its size, you might not be able to obtain a blood sample from a peripherally inserted central catheter (PICC). For example, drawing blood from small-gauge PICC lines (2 or 3 French) can be difficult. Although sources vary, the Infusion Nurses Society recommends using the distal port of a multi-lumen catheter for blood sampling. The distal port is largest (16-gauge) and has a greater flow rate.
Blood collection tubes must be drawn in a specific order to avoid cross-contamination of additives between tubes. 1  The recommended order of draw for plastic vacutainer tubes is: 2  First - blood culture bottle or tube (yellow or yellow-black top) 3  Second - coagulation tube (light blue top). If just a routine coagulation assay is the only test ordered, then a single light blue top tube may be drawn. If there is a concern regarding contamination by tissue fluids or thromboplastins, then one may draw a non-additive tube first, and then the light blue top tube. Third - non-additive tube (red top) Last draw - additive tubes in this order: SST (red-gray or gold top). Contains a gel separator and clot activator.
