An example of an optimum specimen/test match would be a first morning specimen … Specimen collection and processing procedures Proper specimen collection and handling is an integral part of obtaining a valid and timely laboratory test result. If, by contrast, the venipuncture is difficult with much searching for the vein, the blood flow is slow, or the collection is made into a large syringe, the coagulation cascade may become activated; in that case, an initial blue top tube should be filled, discarded and a second filled tube should be collected for testing. The tubes are stocked in the Memory & Aging clinic and are available from laboratory processing areas at each hospital. Learn about insights, research, case studies, and tutorials on integrating remote specimen collection, microsampling, and more! hbspt.cta._relativeUrls=true;hbspt.cta.load(1806452, 'ebcca632-e4f0-4c33-b655-8b79ea18fa4b', {}); Originally published Mar 2, 2017 6:42:00 AM, updated on September 22, 2020. dorsal hand veins.
