Filling Glass Capillary with Blood Obtained by Venipuncture
When the capillary is filled with the sample, analysis must begin within 5
minutes.
1. Mix the sample well (by inversion or use of a tube mixer) to prevent
separation of red blood cells and plasma.
2. Remove stopper from blood collection tube in such a way that a small
sample of blood remains on the stopper.
3. Hold the capillary holder at an angle.
4. Touch only the tip of the capillary to the blood sample on the stopper.
NOTE: Do not attempt to fill the capillary by touching the glass capillary to
blood in a blood collection tube. Attempting to fill the capillary in this manner
most often results in blood touching the capillary holder. If blood touches the
capillary holder, discard the capillary holder.
