Blood Sample Collection
Use a sterile lancet to prick the fingertip‚ apply gentle pressure‚ and collect a drop of blood․ Place the drop onto the test strip‚ ensuring full contact․ Avoid squeezing the finger to prevent hemolysis! Ok․
Sample Volume
The Accu‑Check Aviva requires a minimal blood volume of approximately 0․2 µL for accurate measurement․ This small quantity is achieved by a fine‑point lancet that creates a controlled puncture on the fingertip․ After the prick‚ a gentle tap on the finger encourages a single drop to form‚ which could dilute the sample with interstitial fluid․ The device’s test strip is engineered with micro‑capillary channels that automatically draw the required volume into the sensing area․ If the drop is too small‚ the strip will display a “low sample” warning‚ prompting the user to repeat the puncture․ Conversely‚ an overly large drop may overflow the strip‚ potentially causing a spurious result; in such cases‚ the user should wipe the excess and allow the strip to absorb the correct amount․ Proper technique involves positioning the lancet at a 45‑degree angle‚ ensuring the finger is relaxed‚ and using a clean‚ disposable lancet to prevent contamination․ Consistent sample volume is critical for reproducibility‚ especially when monitoring tight glucose targets or adjusting insulin doses․ The manufacturer recommends using a new lancet for each test and following the device’s calibration schedule to maintain precision over time․ By adhering to these guidelines users can reliably obtain accurate readings with some discomfort and optimal device performance․
Test Strip Preparation
Before inserting a strip into the Accu‑Check Aviva‚ ensure it is stored in its original packaging to protect it from moisture and dust․ Remove the strip from the foil‚ keeping the protective cap on until the moment of use․ When ready‚ gently peel the cap‚ exposing the strip’s sensor end․ Avoid touching the sensor area with fingers or any surface‚ as oils can interfere with the enzymatic reaction․ Place the strip into the device’s strip slot‚ aligning the sensor with the indicator․ The machine will automatically detect the strip and display a ready‑to‑test prompt․ If the strip is not inserted correctly‚ the device will flash an error‚ prompting the user to re‑insert․ It is essential to use only strips that match the device’s model number; incompatible strips can lead to inaccurate readings or device malfunction․ Keep unused strips in a cool‚ dry place‚ and replace them before the expiration date indicated on the packaging․ Following these steps ensures optimal contact between the blood sample and the sensor‚ leading to reliable glucose measurements․ Ensure the strip’s sleeve stays intact until insertion‚ as damage can compromise sensor integrity and accuracy‚ reliable results․
