1 If a person is diagnosed with diabetes, then the physician may recommend regular HbA1c tests in the future. 2  Depending on the type of diabetes, the patient may need to undergo the HbA1c normal range test after every 3 to 6 months.ed blood cells typically live for approximately 120 days in the bloodstream. This allows an HbA1c range test to determine the levels of sugar occurring in the body for over the past 3 months. As compared to regular monitoring of glucose carried out at home, an HbA1c range test is more reliable and relatively better.
African-American chemist Percy Julian was a pioneer in the chemical synthesis of medicinal drugs such as cortisone, steroids and birth control pills.
It was the first extended-cycle birth control pill designed to supply an active dose of hormones every day to completely stop your period for a full year. Each pack of Lybrel contained 365 pills that were made up of 90 micrograms levonorgestrel and 20 micrograms ethinyl estradiol. Lybrel was approved for use by the U.S. Food and Drug Administration on May 22, 2007 as the first, and only, birth control pill that was designed to eliminate women's monthly periods.
