This video explains the process of creating dried blood spots (DBS) from venous blood samples, a technique commonly used for the collection and storage of blood for various assays. DBS offers a convenient, non-invasive method to analyze blood components while ensuring sample stability and ease of transport.
DBS is a valuable tool in clinical diagnostics, disease monitoring, and drug testing, offering advantages such as ease of collection, minimal sample volume, and long-term storage capabilities.
Key Steps Covered:
1. Blood Collection – Properly drawing venous blood into a collection device, typically a capillary tube or syringe.
2. Spotting the Blood – Dropping a small amount of blood onto a special filter paper in a controlled manner, ensuring even distribution.
3. Drying Process – Allowing the blood spots to air dry at room temperature to preserve the integrity of the sample.
4. Labeling and Storage – Proper labeling of the dried blood spots and guidelines for storing the samples, typically in a cool, dry environment to prevent degradation.
