Default blood meter accuracy

I tested my blood sugar this morning 3 times in a row, and the readings were 120, 102, 109. Shouldn't the readings be a little more stable than this?

The variance in meter readings can be up to +/- 20%, so it can vary that much - but usually doesn't, especially in the lower range. Then, also, blood is not homologous and one bit can have a higher glucose concentration than another.

It might also be a faulty strip, or there was something on the finger that had some sweetness to it. If one gets an unexpected number, it is always a good idea to test again.

If it were me, I'd throw out the 120 and go with the other readings.

I agree with VeeJay....

When I first started on LCHF lifestyle, using my meter 5-7 times a day until I learned what foods worked and did not work for me....I worried a lot about how accurate my meter/tabs were.

In time I learned that what really counts is the trends, up, down, or flat! A trend, simply defined, is usually a minimum of 3 occurrences (From Statistics) So I used that a lot. I also targeted my highest acceptable blood sugar (BS)reading was 120! Knowing that 140 is the actual point that cell damage can occur, using 120 should protect me even if the meter is not accurate.

PS....I went to have my regular blood work done two weeks ago. When I got up my BS was 101, about an hour later when they took my blood it came back on the report as 103. Therefore, the meter I have now seem to be pretty darn good....

Good Luck

The meter reading seems to be good on a long average. I tested my BG several times a day for a couple months, and my A1C was within .1 of what that doctor said. But now I'm not checking multiple times a day, I'm starting to test various foods to see what I can and can not eat. I was hopping to be able to eat a new item and one hour later check my BG and decide if I should continue to eat it or not.

I'd recommend checking a new food at least twice, to eliminate (hopefully) any variables.

I've actually wondered about the accuracy of the strips. I was getting higher readings with the last batch of strips. I bought new strips, and my readings have been low. The other day, my fasting BG was under 100! I have never had a fasting BG under 100. I'll take it. I'm not complaining.

STEVENC...

Most of us test new foods at 1hr. after the first bite, then again at 2hrs. and then many, like me, test at 3hrs. Believe it or not, some foods I have tested do not show a major impact until after the 1st hour. This is common when the food being tested or food I ate with the test food has lots of fat. This actually slows digestion.

We also have a process called "Retrograding" that can be done with Potato Salad, and Tuna Salad. This process reduces the starch within the potatoes and pasta used in these foods. If done properly, my blood testing proves I can eat a cup or so of these 'treats' without blowing up my blood sugar....this was a big find for me as it added two favorites back into my lifestyle. Some folks on here also have retrograded rice, but when I tested this it failed...no rice for me. Below is my recipe for the potatoes....the process for retrograding must be followed and never rewarm any food you have retrograded......

Diabetic Retrograded Potato Salad

Retrograde a bag of small red waxy potatoes cut in half or quarters, skin on.

To retrograde potatoes... use small, whole, red new potatoes. Cover with water, cover the pan, bring to a boil, reduce heat, simmer about 30 min. or until done, but not mushy. Drain, leave the lid on and let stand until room temperature. This could take several hours. (Slow cooling is the key.) Make the potato salad and refrigerate 24 hrs. Before eating.

Never reheat retrograded potatoes, pasta, or rice....

As far as how many potatoes…they filled up a 2-quart saucepan about ⅔ full

Add panful of small red potatoes, cooked and cooled per retrograding procedure (above) to large bowl
4 - 5 tbsp. cider vinegar
4 jumbo eggs, hard cooked & diced
2 - 3 big spoonful’s sugar free pickle relish
2 large ribs celery, diced
1 bunch scallions, diced

Dressing:
cup full fat mayonnaise
cup full fat sour cream
1/4 to 3/8 cup prepared mustard of choice (5 or 6 tbsp.)
1 tsp. mustard seed
1 tsp. celery seed
celery salt to taste
fresh ground black pepper to taste

Dice potatoes including skins & sprinkle with vinegar - toss to coat.

Add remaining ingredients, tossing to combine, and then add the dressing - mixing well to coat. If it needs to be creamier, add more mayo.

Chill for 24 hrs. hours before serving.
