NHA Phlebotomy Technician Certification - Additional Info Sample Questions

Which of the following is higher in capillary blood?

Correct Answer:
glucose


when comparing capillary blood to venous blood, it's important to understand that while the concentrations of many substances are similar in both types of blood samples, there are some notable exceptions. among these, glucose levels tend to be higher in capillary blood compared to venous blood.

capillary blood is the blood that fills the microvascular system, including the tiny capillaries that link arterioles and venules. this blood is typically obtained from superficial pricks, such as a fingerstick, and is commonly used for glucose monitoring, especially in diabetic patients. the higher levels of glucose in capillary blood can be attributed to several factors, including the immediate availability of glucose from arterial blood which has not yet undergone full systemic circulation and utilization by tissues.

on the other hand, venous blood is collected from veins, which carry blood back to the heart after nutrients and other substances have been delivered to cells and tissues throughout the body. since venous blood reflects the removal and processing of nutrients like glucose by various tissues, its glucose concentration is generally lower than that found in capillary blood.

when considering other substances such as hemoglobin and potassium in serum samples, similar trends can be observed where their levels might also be higher in capillary blood. this difference could be influenced by the localized metabolic processes occurring in tissues that the capillaries supply, which might not be as pronounced in venous blood reflecting a more systemic state.

therefore, especially in clinical settings where precise measurements of glucose are crucial, such as in the management of diabetes, it is important to note the type of blood sample being analyzed. monitoring and interpreting glucose levels accurately ensures better management of glucose-related conditions using either capillary or venous blood samples depending on the situation and required accuracy.
