14 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Have all supplies ready. Make sure that the cuvettes are “in date”. If opening a new vial of cuvettes, write the date opened on the vial.

15 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Have the analyzer turned on and the cuvette holder in the outer position. The display will show three flashing dashes and the HemoCue symbol. Take a cuvette out of the package. If a vial is used, make sure to replace the cap immediately.

16 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb The patient should be seated. Make sure that the hand is warm and relaxed. It is best to use the middle or ring finger. Fingers that have rings on them should not be used for testing unless the rings are removed.

17 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Clean the fingertip with alcohol. Wipe off the alcohol with a clean, dry, lint - free wipe, i.e. Celltork wipe or gauze, or allow to air dry completely.

18 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Prior to performing the puncture, “prime” the fingertip by applying pressure at the upper joint with your thumb, using a rolling motion towards the tip of the finger.

19 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Prick on the thumb side of the chosen finger. This allows the blood drop to rest on top of the finger for collection into cuvette. Prior to activating the lancet, press it firmly against the finger on the surface facing upward, as shown in the picture. This will aid in obtaining a good sample.

20 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb After the puncture has been made, apply gentle pressure as needed to extrude a large drop of blood. Do not “milk” the finger! Release the pressure on the finger and wipe off the drop with a dry lint-free wipe. Wipe away an additional one or two large drops.

21 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Hold the cuvette opposite the filling end and insert the tip of the cuvette into a large drop of blood. Hold the cuvette in place until the entire teardrop shaped cavity is filled with blood. It is not enough to fill the eye of the cuvette! If the cuvette is not completely filled, discard and use a new cuvette. Do not add blood to a partially filled cuvette!

22 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Wipe off the excess sample from the outer surfaces of the cuvette with a lint-free wipe, i.e. Celltork wipe, as if wiping butter from a knife. Be careful not to touch the open end of the cuvette with the wipe. (This may cause blood to be removed which could produce an erroneous result.)

23 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Place the filled cuvette in the cuvette holder. This should be performed within 10 minutes after filling the cuvette. Push the cuvette holder to the measuring position.

24 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb The hemoglobin value of the sample will be displayed within15-60 seconds. The result will remain on the display as long as the cuvette holder is in the measuring position. (If operating on battery power, the analyzer will shut off after approximately five minutes.)

25 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb Dispose of the lancet, cuvette, and other biohazardous material as required according to local policy.

26 USDOC41 Rev 0 1/04 Training and Education Program ©2004 HemoCue, Inc. Capillary Sampling – Hb When testing is completed for the day, turn off the analyzer, remove the cuvette holder, and clean with a mild soap solution. Dry the cuvette holder completely before reinserting into the analyzer.
