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.
Percy Julian worked through situations that were never ideal, and made the best of them because of his desire to make difference and contribute to the benefit of the larger society, even if it was the one that, ironically, held him back from being a truly great chemist, which in his eyes, he never was.
