Human genetic variation is the genetic differences both within and among populations. There may be multiple variants of any given gene in the human population (genes), leading to polymorphism. Many genes are not polymorphic, meaning that only a single allele is present in the population: the gene is then said to be fixed.
Expense of the blood glucose test strips. Over time, test strips are often the most expensive part of monitoring your blood sugar, so keep in mind the cost of compatible strips when choosing your glucose monitor. On average, glucose test strips range from 35Â¢ to $1.00 each.
A number of you took the opportunity on the LifeScan cringer discussion here to point out how insanely expensive glucose test strips are. Bravo! There is no doubt we get gouged on these things, which cost about a dollar apiece (!) and most of us -- at least most Type 1 diabetics -- use an average of 10-12 per day. I'm crappy at math, but my Casio calculator tells me that's about $4,000/year for the strips alone.
