From Dr Yun-Ching Chen: Include a collapsable stand (can even be made of cardboard) to hold the tubule in place for those who don't have a partner around to help steady the tubule during the collection for the Microtube collection. I like to utilize tests that do not require additional effort on behalf of the patient to find and pay for a phlebotomist. This is an additional expense that is not covered by insurance with these various expensive tests...
