capillary blood samples

Capillary blood samples are small blood specimens taken from tiny capillaries, often in the fingertips or earlobes, rather than larger veins. This method is commonly used for quick tests, such as measuring blood sugar levels or performing blood screenings in infants. Because it requires just a small amount of blood, it's less invasive and quicker than traditional venous blood draws. Capillary samples can provide valuable information for diagnosing various health conditions and are often preferred in emergency situations or routine checks where only a small sample is needed.
