AskNadia: My Walgreen’s True Metrix Lancet Gauge

Dear Nadia,

I bought the Walgreens blood glucose test meter True Metrix, made by Trividia Health. In the box was a package of lancelets that contained long needles, medium length needles, and short needles. 

I have learned that lancet needles ranged from 28 gauge to 30 gauge, and the length range was between 2.8 mm to 3.2 mm. No one has been able to tell me when each of the needle lengths would normally be used, or how to tell me what the middle length measurement would be.  I can only find the short needle length lancelets, but they do not work well in the tool.

Could you please give me your comments on Trividia Health units and lancets, and where I could find the middle length lancelets.
Anne

Dear Anne:

The lancet gauge and length is provided to accommodate different skin textures. Some people have soft skin while other have calloused, hard skin. The gauge and length of the lancets really depend on your skin type. If you are new to diabetes, finding the right lancet that does not bruise you or create too much discomfort can take time. By experimenting with the 28, 30 or 33 gauge with the different depth option from your lancet device, will help you determine which is the best lancet for you in terms comfort and drawing blood for your glucose test strip.

When you buy a kit by Trividia, the makers of the True Metrix, they have already anticipated the different skin texture. By offering a selection of lancets in their diabetes kit,  it gives you the opportunity to see which lancet works best for you.

For example, if you have thick, callused fingers, using a 28G or larger could be more suitable. If your skin is thin with delicate fingers, you may use a 33 gauge lancet.  The gauge of the needle and the depth setting on the lancing device is what is essential in drawing the right amount of blood for your blood glucose test.

One way to remember the gauge size and who  it may be suitable for; the smaller the number listed as the gauge, the thicker the needle; the larger the number listed as the gauge, the thinner the needle.

Trividia offers three lancet gauges which you should be able to buy at Walgreen’s. If not, I would check Amazon.
