The micro systems designed by Guest Scientific offer the facility to make an estimation of the ESR value on very small samples of blood – i.e. 240 µl minimum.
The Micro-Dispette tube is manufactured with a 1mm diameter bore but still includes the full 200 mm length of printed graduations.
The micro method has been shown to correlate well with the full Westergren method, particularly in the normal range. (1) Where supplied, the uncapped white filling reservoir does not contain citrate or saline diluent; hence operators are able to select their own preferred anticoagulant and or diluent, which must be in accordance with the classic Westergren method of 4 parts blood sample added to 1 part diluent.
Full instructions are included in both packs.
The Micro Dispette is available as:
The Micro-Sed pack contains 100 pipettes and reservoirs
Micro Plugged Dispette (FH-1530M)
The Micro-Plugged Dispette pack contains 250 pipettes only.
This method will require a suction pump to fill the pipette with the blood sample.
