Blood Additive are the chemicals that are used in storing blood specimen carried out for clinical laboratory investigations.
Different Blood additive or Anti-coagulants are used in different types of requirement.
The additive in the purple tube is EDTA (ethylenediaminetetraacetic acid), which is an anticoagulant. This additive is used primarily in blood collection tubes for hematology tests, as it helps to prevent blood from clotting by binding calcium ions. The purple tube is commonly used for complete blood counts (CBC) and other tests requiring whole blood or plasma.
Vacutainers come in a variety of colors to denote the type of additive or treatment applied to the blood sample. Common colors include red (no additive), lavender/purple (EDTA additive), light blue (sodium citrate additive), green (heparin additive), and gray (fluoride oxalate additive). Each color signifies a specific purpose in preserving or treating the blood sample for laboratory testing.
If a blood sample is collected into an evacuated tube without an additive, the blood will clot naturally because there is no anticoagulant present to prevent clotting. This can lead to inaccurate test results as the clot formation may interfere with various analyses requiring liquid blood.

Non additive red top
The color top tube used to collect whole blood with an additive is typically a lavender or purple top tube. This type of tube is commonly used for collecting blood samples for hematology testing.
The color of test tube typically used for blood cultures is a yellow tube with an SPS (sodium polyanetholsulfonate) additive. This additive helps prevent the blood sample from clotting and maintains the viability of microorganisms in the sample for culture.
The stopper used for hemoglobin blood testing is lavender, and the additive is EDTA.
There was no information found that confirms pigs blood is an additive in instant coffee. Instant coffee is made from coffee beans that have been brewed and then either freeze dried or spray dried.
EDTA (ethylenediaminetetraacetic acid) is the additive put in the tube for Complete Blood Count tests to keep it from clotting.
For most of the blood tests fasting blood specimen is required
Sodium fluoride is an additive that prevents glycolysis by inhibiting the enzyme enolase. This helps preserve glucose levels in blood samples for accurate laboratory testing.
