You Try It (testing in the dark)

You need to test your blood sugar.

It’s the middle of the night.

This is what you see.


You have your testing kit. But now what?

You need to get a test strip. Not too hard.

You need to insert the correct end into the meter with the right side up. What’s that? You can’t see? How can you tell if the strip is in right?


Poke your finger and squeeze out a drop of blood. Did your poke work? Do you have enough blood? Do you have TOO MUCH blood? Your not bleeding all over your bedding, are you?


Now apply the blood sample to the correct spot on the strip. What? You can’t see? How will you know if you’re getting the strip anywhere near the drop of blood?


Device manufacturers, I ask you to imagine interacting with your diabetes devices in many different scenarios. Imagine needing to test your blood sugar at 3:00 AM. If you are a parent, imagine needing to test your child’s blood sugar at 3:00 AM. You expect US to be able to pull this off.

Turning on a light is not always feasible.

And what about those who are visually impaired? Aren’t they “testing in the dark” all of the time?

Scott, Here is another issue to add to your collection….. What if the person with Diabetes has a level of blindness. Everyday stuggles are difficult with proper lighting. Imagine how difficult it can be for them. Here are some suggestions: A brail point on one end of a strip Electronic annoucement, “Your reading is 89” A tone if the sufficent blood has been applied and reading is in process. If electronic software designer can design a game that throws a bunch of birds across the screen and knocks down a bunch of bricks and walls. Imagine what they could do… Read more »

I use my Dexcom as a flashlight while I fumble around in the dark. I have also used my iPad to light up my finger. You are right Scott. Someone needs to design a meter with a night setting. A gentle light around the strip. Maybe a light up lancing device. Not blinding like turning on the bathroom light, but a soft glow like a nightlight. First manufacturer to create one wins my business.


So flipping true. Maybe they think PWD’s have nightvision or something? That would be a sweet “complication.”

Thank you for (wait for it) bringing this need to light. 😉

The Verio IQ light is really nice, but at night the screen is blinding. So I put my hand over the screen so I can take advantage of the light at the front. I so wish they’d put a light sensor in there.

After years of testing without a light, I don’t know if I can go back to darkness again. Thanks for the great post Scott.


Not to hijack this blog topic, but I happened upon your A1c page and noticed your latest A1c was below 7! Just wanted to congratulate you on such a huge accomplishment. =)
