Back to Meters InDuo

The InDuo is no longer available. This review is here for historical purposes.


The InDuo is the world's first combined blood glucose meter and insulin dosing device. The glucose meter uses the same test strips as the OneTouch Ultra and offers 5-second testing, 1 microliter blood volume, and alternate site approval. The insulin doser offers the same advanced functionality as Novo Nordisk's Innovo, including a memory of the number of hours since delivery and amount of the last dose. For those who use or are interested in using an insulin pen, the InDuo is highly recommended.

Blood Glucose Testing
Testing with the InDuo is as easy as the OneTouch Ultra. You must first be sure the meter is calibrated to the vial of test strips. With that out of the way, you simply insert the test strip (the meter turns on automatically) and touch the blood sample to the strip. You can touch the strips while inserting them into the meter. Your test result will be displayed in 5 seconds. The InDuo is easy enough to use that even young kids will be able to use it by themselves. The test strips are very thin and flexible, however, and thus require a little more attention when inserting into the meter than test strips for some other meters.

Personal computer users can use IN TOUCH, LifeScan's diabetes management software, to produce an array of detailed analysis of blood sugar data downloaded from the InDuo. A special data interface cable is required, but the software can be downloaded for free from the LifeScan web site.

Insulin Dosing
The insulin doser in the InDuo is essentially Novo Nordisk's Innovo, an innovative pen-like device. The InDuo doser uses only Novo's 3ml cartridges, so you need to use Novo insulin to use the InDuo. A wide variety of insulin is available in this form, including NovoLog, a rapid-acting insulin analog. Loading up a cartridge is easy, as is dialing up a dosage amount and injecting. Dosing is in one unit increments -- no half-unit dosing is possible. During dosing, the InDuo doser display changes to show when it is time to take the needle out (six seconds). The doser also shows the amount of the last dose and, in a dial-like fashion, the number of hours since the last dose was injected. While pen makers discourage leaving needles attached, the InDuo doser fits inside the meter housing with or without a pen needle attached.

Key features of the InDuo include:

  • Fast test results -- 5 seconds
  • Small blood volume (1 microliter)
  • Alternative site testing
  • End-fill test strips that can be touched
  • A 150-test memory for storing blood sugar readings
  • 14- and 30-day averaging
  • Large, easy-to-read display
  • Data interface port
  • Uses one standard watch battery (rated for approximately 1,000 tests)
  • Displays blood sugar readings in mg/dL or mmol/L
  • Integrated NovoPen insulin doser rated at 4,000 injections

Combining the highly-rated OneTouch Ultra glucose meter with an integrated, advanced insulin dosing device, the InDuo delivers a new level of convenience for people with diabetes who are comfortable with pen injectors and who can live with one unit granularity in dosing. For insulin pump users, the InDuo offers the convenience of always having backup insulin at hand. If you routinely mix short and long acting insulin in a syringe, you may not find any advantage in the InDuo. If you can live with one unit dosing granularity, the InDuo is Highly Recommended.
