Do Ketone sticks expire?

[TheQuietRioter]

I have been using ketone sticks that are 7 years old, and I am not sure if they are working properly.

I can only seem to get a trace reading, which is a really light pink or sometimes it looks lilac. I am on my 13th day of Induction, and I started testing with the strips after the 3rd day, and about every other day thereafter.

But, I am losing so far on Induction.

I was just curious if they go bad after a period of time.

They do expire. You should see an expiration date on the side of the container.

I did look for the exp. date, but could not find one.

It was probably so long ago they may have only been on the outside of the box it came in. You can get a good generic for around $10.00. They are well worth the expense.

there should be en exp. date somewhere on the container. mine reads 2010-01... something in this format..
You will probably get a false reading with the old sticks. Every reagent expires.. and every pharmaceutical and cosmetic product do have an expiration date.. even shaving creams and toothpastes..
