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.
I live in Canada and bought a new blood glucose monitoring system last year, and now it's time to buy new replacement test strips. I was a bit taken aback by the price. $89 for 100 strips in one shop and $120 in another. 50 strips was $52.
