Principle: This tube contains a measured amount of sodium citrate. Citrate is a reversible anti-coagulant. Because the liquid citrate dilutes the blood, it is important the tube is full so that the dilution is properly accounted for. Inadequate amounts of blood in the tube can give erroneous test results. The mixing ratio is 1 part citrate to 9 parts blood. |
