LifeScan ONE TOUCH FastTake with new FastDraw strips LifeScan FastTake Meter

LifeScan will no longer make the FastTake Blood Glucose meter effective November 10,2001. Consider the LifeScan Ultra model, which has received excellent reviews. (FastTake was also marketed under the brand names: SmartScan®, EuroFlash® and PocketScan®)

Differences from the Elite XL

FastDraw strip design is similar for Ultra and FastTake meters.

June 9, 2000, LifeScan released a new capillary action "sip-up" style of FastTake Strip called the FastDraw design, similar to the Bayer Elite and Accu-Chek Comfort Curve strips.  Place the top white edge of the strip to the blood drop and let it "sip-up" until the confirmation window is completely filled.  When the red blood covers the white/gray squares, you have gotten a sufficient sample.

Blood Glucose Meters Considerations

The primary considerations are small sample size, ease of meter use, and ease of obtaining a reliable sample. Pets will move when you try to test them. If a meter is fussy about the angle that you have to hold it to get an accurate sample (such as the Dex), that may outweigh all the other advantages.

Troubleshooting

If you think you may not be getting an accurate BG, check the following:

Specifics are for the Elite XL, check your manual for your meter's specifications and procedures.

  1. Look at the strip. Was it filled enough to give a sufficient sample?
  2. Check that the strips weren't expired and that the strip F code matches the meter setting.
  3. Temperatures ok for strips (store at 59-86 F), and meter operating range 50-104 F?
  4. Once the foil is opened, the Test Strip should be used immediately. The sensor uses a chemical reaction to measure BG, which deteriorates with exposure. Discard any partially-filled strip, you can't add more blood to it during another cycle and get an accurate reading.
  5. Use the Check Strip (says CHECK) to test the meter electronics.
  6. Use the Normal Control Solution to check that strips read in the specified range (ex.78-112 mg/dL on F-2 strips). A High Control Solution is available which tests the meter accuracy at higher BGs (ex.250-339 mg/dL on F-2 strips), which is still much lower than many unregulated cats' BG level without insulin.
  7. Call Customer Service for more help, or if the meter appears to be malfunctioning.
  8. Severe dehydration, which may be caused by vomiting and/or diarrhea, can affect BG reading with capillary blood.

Meter Accuracy Varies in Measurable BG Range

The manufacturers of home glucose meters use a technology that provides the most accuracy around 100 mg/dL BG, which is in the normal range (for humans and for cats). The meters read slightly lower BGs in the hypoglycemia range but may be quite a bit lower than actual BGs in the hyperglycemia range. A given meter will reliably reproduce similar numbers in the same range, when a BG test is immediately repeated, assuming both samples were sufficient, the meter is within specifications for operation, and the meter electronics check out ok (Elite has a CHECK strip).


The Bayer Elite reads progressively lower as the BG number goes higher.

Here are correction factors one person measured for his Elite by doing a vein draw and ear prick at the same time on his diabetic cat, over a period of several days, to get samples at various BG's. This was all done with the assistance of a vet. The venous sample was collected, centrifuged, and hand-carried to the local IDEXX lab for testing. The results are what you see, the difference between an ear prick with the Bayer Elite and a venous sample measured at IDEXX., expressed as Correction Factor, compared to a laboratory capillary plasma glucose standard. Other Elite meters may have different corrections, these figures were not provided by Bayer.

Multiply the Elite BG reading by the Correction Factor to get the Lab Value.

Also, a venous whole blood sample usually reads higher than a capillary sample, when read with the Test Strip on the Elite. Bayer claims about +7% higher for humans. That is, if you take blood from an ear prick and a vein at the same time, and test both bloods on the Elite, the venous blood will give a higher BG reading.

The error table above is typical of many home glucometers, and this is one reason why high BG readings on home glucometers should be taken seriously. For example a 390 reading may be closer to 470 actual, and a 500 reading is more like 640 actual. This is why the meters cut off at 500 or 600. The readings are so inaccurate at these high levels that they aren't allowed to display.

Remember, these home glucometers are designed for humans, where the typical BG range of interest is 75 - 200. The high BG's over 200 are used as warning signals for humans and most larger animals - as these are very damaging long-term, and never tolerated. Hence the accuracy of the meters is best where the control regime is desired for humans, around 100. Fortunately, cats tolerate high BGs much better than people; talk to your vet about what range to target for your pet. [from the archives of the Feline Diabetes Message Board, Posted by Jud & Call]


Which Numbers do you Believe? Meter vs. Vet vs. Outside Lab

Human diabetics trust their lives to their meters. The pattern of results you get with your meter will correspond to your pet's behavior and you will come to know what the numbers mean for your individual pet. When Harry goes over 500, he is more lethargic--he just doesn't feel very good. His volume of urine output increases (PU) and his control/ability to get to the litter box in time diminishes (more accidents). When he is around 200, he will be more alert, interested in playing, and we never have a urine accident.

You can take your meter with you and check your pet's blood glucose with an ear prick (capillary) on your meter at the same time (within 5 to 10 minutes) that the veterinarian draws blood from a vein (venous). The newer meters are all calibrated to display plasma results when capillary blood is tested, so you can directly compare the Elite results with your vet's or an outside lab. NOTE: some vets are starting to use home glucometers in their practices, ask what they use. The meter reading and laboratory values should not vary by more than 15-20 percent. If your meter reading appears to be way off from the vet's test equipment, despite passing all its Check and Control solution tests, a 3-way check by sending some of the venous blood to an outside lab can help to determine if it might be the veterinarian's lab equipment that is out of calibration. Recent ingestion of food can elevate the capillary blood up to 70 mg./dL higher than blood drawn from a vein for a lab test, reversing the pattern seen on fasting, where venous blood BGs are higher.
