Getting a good capillary blood sample

To get a suitable drop of blood:

n Warm the hand. Have the patient hold it under his or her arm, use a hand warmer, or wash

with warm water.

n Have the patient let that arm hang down by his or her side before lancing a finger.

n Massage the finger from its base.

Use these techniques until the fingertip has increased color.

n Immediately after lancing, massage gently along the side of the finger to obtain a good

blood drop without pressing or squeezing too hard.

n Apply the blood drop directly to the test strip immediately (within 15 seconds).

Optionally, you may use a CoaguChek Capillary tube/bulb to collect the fingerstick blood

sample (REF 11621173001).

Getting a good test with venous whole blood

As an alternative to performing a test with capillary blood, you can also perform a test using

venous whole blood. Please note the following:

n Use a plastic syringe to collect the blood sample. Do not use anticoagulants (EDTA, citrate,

oxalate or heparin) to collect the blood sample.

n Use a needle at least 23 G or larger in size.

n Discard the first four drops of blood. Then, immediately place one drop of blood (at least

10 µl) directly onto the target area of the test strip, being sure not to introduce air bubbles

into the sample.

Follow the appropriate infection control guidelines in force in your facility.

n Use gloves.

n Use a lancing device that is approved for use by healthcare professionals.

n Dispose of used lancets and test strips in a sturdy sharps container with lid.

n Follow all health and safety regulations in force locally.

Testing a capillary blood sample

Medical staff and other persons using the CoaguChek XS Plus meter to

perform tests on more than one patient must be aware that any object

coming into contact with human blood is a potential source of infection.
