capillary specimen

capillary specimen

A small blood sample taken by lancing a fingertip and placing one end of a capillary tube at the edge of the blood drop. The blood migrates up the tube by capillary action.

Tests commonly performed using capillary blood:
• Point-of-care testing—e.g., blood glucose monitoring;
• Complete blood count (CBC), haemoglobin and haematocrit (H&H);
• Peripheral blood smear—manual slide for white blood cell (WBC) differential;
• Neonatal blood gases;
• Neonatal bilirubin;
• Neonatal screening (filter paper or blood spot testing);
• Electrolytes;
• Serum lead in children.

Among 50 facilities, 30 (60%) had a written procedure for routinely retesting critical POCG results using a venous blood specimen (n = 9), a new capillary specimen (n = 8), both venous and capillary specimens (n = 7), or either capillary or venous specimens (n = 6).
But it wasn't known if the test results from a capillary specimen were an accurate reflection of a child's serum lead level.
Repeat testing to confirm critical value results was allowed to be performed on another capillary specimen using the glucose meter, on a venous specimen tested by an alternative point-of-care device (RAPIDPoint 405 Systems, Siemens Medical Solutions USA, Malvern, Pennsylvania), or to be sent to the laboratory for testing on chemistry analyzer (VITROS Systems, Ortho-Clinical Diagnostics, Inc, Rochester, New York).
Serum bilirubin level, typically measured in a capillary specimen obtained by performing a heel puncture, is critical in the management of neonatal jaundice.
What is the specimen volume required for closed tube, open tube, and capillary specimen analysis?
Redrawing might also be necessary to make sure that an arterial specimen is indeed arterial, or that a capillary specimen from an infant is correctly drawn on ice, mixed, and immediately transported to the laboratory for blood gas analysis.
The tube has a pierceable cap, which allows it to be processed in the automated mode on hematology analyzers, thereby, minimizing laboratorians' hands-on time in processing capillary specimens.
It brings nearly 100 plastinated specimens, among them entire animal bodies, body slices, organs and capillary specimens to guide visitors on a journey through nature's anatomy.
15 K, and below with pumping; a cold-nitrogen-gas blower for capillary specimens in the range 80 K to 373 K; a hot-air blower for capillary specimens up to 950 [degrees]C; a high-temperature oven for spinning flat-plate specimens up to 1600 [degrees]C in vacuum, and 1200 [degrees]C in an oxidizing atmosphere; a capillary cell for condensing volatile samples in situ, or for treatment of samples in different atmospheres or under vacuum; translation stages for mapping residual strain in engineering components.
