Why EDTA was used in tubes for blood collection instead of Heparin?
Aren't both EDTA and Heparin anti-coagulants?
IF so,
why isn't Heparin used?

actually both of them are used. heparin are present in vacutainers which are also used for blood collection. i think the only difference is in the processing time. heparin do have a very short half life so if u think blood will be processed for long period of time it is better to used EDTA.

Catheter-related infections occur in grossly immunocompromised patients like Leukemics HIV infected patients and severe diabetics. A comparison is being made between Heparin and EDTA.
No final authentic results are available.

EDTA is used, but mainly for CBC collections
Heparin is used, but mainly for Prothrombin Time(PT) and INR.
EDTA is not used for PT b/c it chelates calcium.
by chelating calcium a proper PT / INR is not valid.
and EDTA is just cheaper that's another reason why it's used for CBCs.
Heparin on the other hand does not chelate calcium and therefore can give correct PT/INR times.

both are anticoagulants.
use of anticoagulants depends on the type test to be performed in the blood.
using any anticoagulant for any blood test will yield wrong results,which results in misdiagniosis and mistreatment and finally death of a person if treatment is continued.
aniticoagulants are specific for blood tests.
