Getting a good result from
venous whole blood
For sample collection use a standard blood collection
device.
Do not use anti-coagulants
(e.g., EDTA, citrate,
fluoride, oxalate, or heparin) to collect the blood sample.
Venous blood samples may be collected from a venous
line .
If venous samples are collected by
venipuncture
, note
the following:
■
Use a needle at least 23 G (approx. 0.65 mm) or
larger in size.
■
Discard the first
four drops
of blood collected
(within the first 10 seconds). Then immediately
apply one drop of blood (at least 8 μ L) directly onto
the target area of the test strip. Ensure that no air
bubbles are introduced into the sample.
Protection against infection:
When collecting samples always observe the general
precautions and guidelines relating to blood sampling
(see page 17).
Dispose of all test strips used for patient testing in
accordance with the disposal policy of your laboratory or
practice (see page 17)
