SPECIMEN COLLECTION AND PREPARATION FOR ANALYSIS

Capillary blood or venous whole blood containing K2EDTA or lithium heparin anticoagulant may be used.

7.1 CAPILLARY SAMPLING

With gloved hands, take a Consult

Hemoglobin Cuvette out of the foil bag and close the bag. Make sure the

hand is warm and relaxed. Use the middle or ring finger for sampling. Avoid fingers with rings on.

1.Disinfect and dry the puncture site.

2. Gently massage the finger towards the tip to increase blood flow. Avoid going past the first knuckle.

3. Make the incision on the upward-facing side of the fingertip, so that the blood drop sits on top of the

finger, to facilitate filling of the cuvette.

4. Apply light pressure towards the fingertip (but not past the first knuckle) until a blood drop appears.

Wipe away the first 3 drops and make sure there is a free blood flow before filling the cuvette with the

fourth drop.

5. Be sure to have a sufficient sized blood drop to fill the cuvette. Fill the cuvette completely by touching

the corner of the cuvette to the blood drop Do not refill the cuvette. If a cuvette cannot be filled in

one continuous process, or if the cuvette contains air bubbles, discard the cuvette and use a new one,

repeating steps 4 and 5.

6. Gently wipe off the excess blood on the outside of the cuvette with a gauze pad. Be sure to gently

wipe both sides. Do not wipe too close to the open end as this can draw blood out of the cuvette.
