General Specimen Collection and Handling

1. Most of the tests use venous blood samples.

2. To ensure consistent and accurate result:

   • Strictly follow the volume of blood required for each test specified on the label or fill the blood sample to the mark on the label. 

   • Inaccurate blood volume will result in inadequacy for further testing if required.

3. To prevent haemolysis:

   • Avoid vigorous mixing.

   • Send the specimen to the laboratory as soon as possible.

   • Haemolysed specimen will give erroneous result (false reaction, incorrect interpretation, inaccurate blood typing).

4.  Avoid clot formation by:

   • Ensuring a smooth venapuncture and steady flow of blood into the syringe.

   • Introducing the blood into the anticoagulant tube as soon as the blood has been drawn.

   • Mix immediately by gently inverting the tube at least 4 - 8 times.

   • Clotted specimen will cause disruption of cell and plasma separation, inaccurate results, interference with antibody detection and increased risk of complications when wrong blood supplied.
