Guidelines For Using The Memo Chip; Specimen Collection; Fingerstick (Capillary) Whole Blood Samples - CardioChek PLUS User Manual

MEMo Chip is inserted into the port with the finger notch facing up. The MEMo Chip reads
the test strip expiration date, tells the analyzer which test(s) to run, contains the calibration
curve and the lot number for the specific test strip lot, controls test sequences and timing,
and establishes the measuring range for the test. The MEMo Chip contains proper settings
for the test strip lot you are using.

Guidelines for Using the MEMo Chip

• The MEMo Chip must be in place to run a test.
• Use only the MEMo Chip that is included with each package of test strips. The lot
number code on the test strip vial, MEMo Chip, and analyzer display must match.
• If the expiration date in the MEMo Chip has passed, the analyzer will display EXPIRED
LOT.
• If the MEMo Chip is lost or missing, a replacement can be requested by contacting
Customer Service.
The MEMo Chip port is located at the top center of the analyzer. The MEMo Chip is inserted
into this port with the finger notch facing up. Push firmly, but gently, until the MEMo Chip is
fully inserted.

Specimen Collection

PTS Panels® reflectance test strips are designed for use with fresh capillary (fingerstick) whole
blood, or venous whole blood collected in EDTA or heparin tubes. Electrochemical test strips are
designed for use with fresh capillary (fingerstick) whole blood only. For best results, samples
should be obtained from patients in a fasting state (no food or drink, except water, for at least
12 hours).
Caution: Handle and dispose of all materials coming in contact with blood according to
universal precautions and guidelines.
A. Fingerstick (Capillary) Whole Blood Samples
1. Warm the fingers to increase blood flow.
2. Let the arm hang down at the person's side briefly to allow blood flow to the finger tips.
3. Instruct the patient to wash hands in warm, soapy water. Rinse well and dry completely.
When an alcohol pad is used to thoroughly cleanse the finger, cleanse with a firm wiping
motion to ensure the removal of any additional lotion or glycerin-based soap residue,
and then wipe excess alcohol with a clean gauze pad before testing.
4. Use a new sterile, disposable lancet to puncture the side of the fingertip.
