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.
Birth control pills usually contain one or two hormones. These hormones prevent egg release from the ovaries. It also causes changes in the cervical mucus and uterine lining which may make it more difficult for sperm to fertilize an egg. Birth control comes in many forms, but is commonly prescribed in pill form. Patches and injections are alternatives to pills. Common hormone combinations include estrogen / progestin / folate combinations, estrogen / progestin / iron combinations, estrogen / progestin combinations, and progestins.
