Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:

- This tube contains Ethylenediaminetetraacetic acid or EDTA for short. It's cover is usually colour coded lavendar
- This tube is labelled ACD that is Acid Citrate Dextrose. It's top is coded light yellow
- this tube contains Oxalate/Fluoride and it's cover must be colour coded gray.
