A Complete Blood Count (CBC) is not something you "take," but rather a test where a blood sample is collected. Here's how a CBC blood sample is typically taken, based on the provided information:
Steps for a CBC Blood Sample Collection:
- Skin Preparation: The area where blood will be drawn is first cleaned with an antiseptic wipe.
- Tourniquet Application: An elastic band, or tourniquet, is placed around your upper arm. This makes the veins swell with blood, making them easier to access with a needle.
- Needle Insertion & Blood Collection: A needle is inserted into the vein, and the required blood sample is collected in one or more vials.
- Tourniquet Removal: After the blood sample is obtained, the elastic band around your arm is removed.
- Bandage Application: The area where the needle was inserted is covered with a bandage to stop any bleeding.
Essentially, a healthcare professional will perform these steps to collect the blood sample required for a CBC test. You, as the patient, do not take anything yourself, but rather have a blood sample taken from you.
