Implication

Technical report demonstrates a simplified capillary micro-haematocrit tube for blood sampling, indicating an easier method to measure red blood cell volume.

Key Points

To introduce an improved and simplified capillary micro-haematocrit tube for determining packed cell volume and haemoglobin concentration using capillary blood.
Engineered an open-ended capillary tube treated with dried heparin to prevent premature clotting during blood collection.
Developed accompanying equipment including a specialized centrifuge head and a stencil cutter for sample measurement.
Maintained tube preservation by storing the apparatus in spirit and mounting it in a cork for convenient handling.
The open-ended tube design resolves practical drawbacks associated with earlier micro-haematocrit collection devices.
Pre-heparinizing and air-drying the glass capillary simplifies immediate capillary blood sampling without requiring extra liquid anticoagulants.
