Taking a blood sample is essential to diagnose, examine and improve the disease and disorder.2. Sometimes blood samples are also taken to check hemoglobin levels.3. Blood sampling is also very important to check the values ​​and examine the morphology of blood components, including red blood cells (RBC), white blood cells (WBC), and platelets.4. A blood sample is taken before giving the blood to anyone. To see that the donor's blood is compatible with that of the patient, and to see that the donor has no disease and that the blood will not be dangerous for the patient.5. Blood sampling is also important to examine and check the quality of different biochemical parameters in the body, such as blood sugar level, uric acid, blood gases and colestrol level.6. Blood sampling is also very important in all tests like CBC, LFT and RFT etc. Blood collection sites Venous blood collection: The best positions for venipuncture are generally the superficial veins located in the upper extremities. Because the veins are bigger here. If the upper extremity veins are not felt or unavailable, other positions may be used to draw blood. The middle cubital vein is mainly preferred because it lies between the muscles and is easier to puncture. Another advantage of choosing the midvein is that it does not roll or move under the skin. Simply put, it is completely safe to break through. The Basili vein runs through an artery and a nerve. So the puncture here poses a risk of damaging the nerve and the artery, that's more. Puncture of the basilic vein is therefore more painful. The cephalic vein interacts with the basilic vein through the median cubital vein at the elbow. Blood passes from smaller veins and flows into the cephalic vein. It is used in obese patients. Arterial blood collection: The artery is a less common position for blood collection. The most common cause of arterial blood sampling is arterial blood gas testing. The common puncture position is the radial artery in the wrist and the femoral artery in the groin. Blood from the artery can also be extracted from the arterial catheter. Capillary blood sample: Capillary blood sample is necessary when only a small amount of blood is required, such as when testing blood sugar by the glucometer method. The most common capillary blood sample is from the finger, but it is also done from the heels in infants. Finger Blood Collection: The best site for finger pricks is the center of the pads of the 3rd middle and 4th ring fingers of the non-dominant hand. The fingertip should not be used. The side of the finger where there is less soft tissue should also be avoided. Heel blood sample: the suggested area for./
