What are the components of capillary blood?
Regarding pH and gasses, capillary blood is actually closer to arterial than venous blood. Compared to a venous plasma, capillary plasma contains higher concentrations of proteins, calcium and chloride, and lower levels of potassium, sodium, and urea nitrogen.
What is a capillary blood test?
A capillary sample is a blood sample collected by pricking the skin. Capillaries are tiny blood vessels near the surface of the skin.
What test is typically performed on capillary blood?

What is capillary blood test?
Capillary blood sampling, which refers to sampling blood from a puncture on the finger, heel or an earlobe, is increasingly common in medicine. It enjoys several advantages over venous blood sampling: it is less invasive, it requires smaller amounts of blood volume and it can be performed quickly and easily.
What is a capillary test for?
Capillary blood is used for glucose measurements by transferring the blood to a test strip. Differences in Results. The differences between capillary blood versus plasma in most cases are minimal. However, there are some discrepancies in hemoglobin and hematocrit values and in platelet counts.
What is the difference between venous blood and capillary blood?
The differences between capillary and venous blood in most cases are minimal. However, there are some discrepancies in hemoglobin and hematocrit values and in platelet counts. It is well known that capillary blood has higher hemoglobin and hematocrit values than venous blood.
Can a plasma specimen be collected by capillary puncture coagulation?
Glass slide A plasma specimen for this type of test cannot be collected by capillary puncture Coagulation Capillary blood composition more closely resembles Arterial blood The concentration of this analyte is normally lower in capillary specimens than in venous specimens Calcium
What is a dried blood spot ( DBS ) used for?
What Is a Dried Blood Spot (DBS)? Dried Blood Spots (DBS) are whole blood collected on filter paper and dried. They are made directly from the client’s whole blood. DBS are used for re-testing at a reference laboratory, which may be part of your country’s External Quality Assessment plan.
What’s the purpose of blood collection and handling?
Blood Collection and Handling – Dried Blood Spot (DBS) Purpose To provide you with the skills to collect and handle dried blood spots (DBS) for EQA purposes.
