Blood Sampling
Capillary blood sampling can be used to test for, for example, blood glucose (such as in blood glucose monitoring), hemoglobin, pH and lactate (the two latter can be quantified in fetal scalp blood testing to check the acid base status of a fetus during childbirth).
Capillary blood sampling is generally performed by creating a small cut by a blood lancet, followed by sampling by capillary action on the cut with a test strip or small pipe.
