Preparing For Blood Sample
This step is very important: read all directions carefully before you prick your finger. If you are then still unsure about how to prick your finger, call the CholesTrak Help Line.
First wash your hands thoroughly with soap and warm water before you obtain the blood sample. Rinse and dry your hands completely before beginning the CholesTrak test.
Sit down and relax for about 5 minutes. During this time rub your hands to warm them.
Select your "middle" or "ring finger". The finger should be warm and callus-free. (See the area shown in the picture in Step Two for an example.)
TO INCREASE BLOOD FLOW, LET THE ARM OF YOUR SELECTED FINGER HANG DOWN AT YOUR SIDE FOR AT LEAST 30 SECONDS. If you are right-handed, draw blood from your left hand. (Reverse if left-handed.)
DRAWING
BLOOD SAMPLE
Lay selected hand, palm up, against a flat table surface. Don't pull your finger away, you may not get enough blood!
Hold the finger stick device in your other hand as shown in the picture.
Hold the finger stick device firmly against the outside tip of your finger as shown above. With your thumb, press the trigger down until you hear it click. This will take some force. You may feel a slight sting. After the puncture, remove the finger stick CholesTrak device.
With the gauze pad, wipe away the first sign of blood. Blood may not appear until you squeeze your finger.
Before adding blood to the Blood Well, with your finger pointing down, let your arm hang at your side for 10 seconds to increase blood flow.
ADDING
BLOOD TO THE WELL
YOU MUST ADD ENOUGH BLOOD WITHIN 5 MINUTES OF PRICKING YOUR FINGER TO COVER THE BLACK FILL CIRCLE.
Point your finger down directly over the Blood Well as shown above. Squeeze your finger from its base to the puncture several times. Squeeze and release your fingertip a few times to form a hanging drop of blood. Let the drop of blood touch the bottom of the CholesTrak test device Blood Well. Continue adding blood until the black fill circle disappears. For best results, add blood as quickly as possible.
IF THE BLACK FILL CIRCLE IS STILL VISIBLE, CONTINUE ADDING BLOOD. Letting your arm hang down again may help if blood flow is slow. Do not worry about adding too much blood.
ONCE THE BLACK FILL CIRCLE IS COVERED, WAIT AT LEAST 2 BUT NO MORE THAN 4 MINUTES AND START STEP FOUR. Apply the adhesive bandage to your finger while waiting.
PULL TAB--READ RESULT
After waiting, hold the CholesTrak test device firmly in your hand. Pull the clear plastic tab on the right side of the test device until you can see the entire arrow. PULL HARD! Don't worry about breaking the tab or spilling the blood!
Tap the CholesTrak test device on the surface of the table. The "O.K." indicator turns purple in about 5 minutes. The "END" indicator turns green in about 10-12 minutes. READ THE TEST AFTER BOTH INDICATORS CHANGE COLOR. If one or both do not change color, call the CholesTrak Help Line.
Read results under bright light. Find the very tip of the purple color bar in the Measurement Scale, even if fuzzy or faint. You can slide the edge of the result chart along the scale to help find the tip of the color bar. This number is your "test device reading"--not your cholesterol level.
Using the Cholesterol Result Chart, match the number of the column labeled "test device reading" with the number to its right under the column labeled "Cholesterol mg/dL". This is your cholesterol level. If your number is not on the card, call the CholesTrak Help Line.
IMPORTANT: Only the Cholesterol Result Chart that corresponds with your kit can be used to find your test result. A chart from another test kit will give an inaccurate result.
