how is blood collected
1 Answer | add yours
There exists three methods of collecting blood samples: venipuncture method, fingerstick procedure and heelstick procedure.
The venipuncture method is more elaborated than fingerstick procedure and it is required for many objectives: diagnosis, monitoring, treatment, donation. The blood is collected from median cubital vein.
The heelstick method is recommended in case of 0-6 months infants and the puncture is not deeper than 2.5mm, it is not made on posterior curvature on infants' heel.
The optional dermal puncture fingerstick method is done when venipuncture is not indicated and it needs to be performed to avoid the errors that require a new blood sample recollection.
