Helen Murray Frey, a chemist who revolutionized her diagnostic test when she was working together on a blood thinner to test glucose in the urine, was 98 years old in Elchart, Indy.
Stroke has been linked to stroke, says Eric Erik.
Linn Prior to the invention of the dip-and-reading experiment in 1956, technicians continued to add chemicals to the urine and heated the mixture on a Bunsen burner. The test was inconclusive, and, since it could not distinguish glucose from other sugars, the results were not very accurate.
In addition to being a chemist, she worked with her husband to learn how to conceive a chemical filter that turned blue during Frixos’ life. The diagnosis made it easier for clinicians to diagnose diabetes, and the loss of test kits at home cleared the way for patients to control their glucose levels.
Diabetics currently use blood sugar monitors to monitor their glucose levels, but dip-and-reading tests are available in clinical laboratories around the world.
Helen Merry was born in On February 20, 1923, he was in Pittsburgh with James and Daisy (Piper) Murray. Her father was a coal seller; Helen’s mother died of influenza at the age of 6.
In 1941, she enrolled in Voster College, Ohio, with the intention of becoming an English or Latin teacher. But on the advice of her housekeeper, she turned the major into chemistry; World War II was creating new opportunities for women in the field of men.
“I don’t think it’s the worst thing I’ve ever done in my life,” said Fried. Memorial booklet prepared Founded in 2010 by the American Chemical Society.
She received her bachelor’s degree in In 1944, she began working at the Miles Laboratory in the Biochemistry Department of Quality Control and Subsequent Diagnostic Testing in Elcart, and her future husband, Alfred Free. They were married in 1947.
Presented ideas; She was a technician “Who had the chance to choose his brain in 24 hours?” Linn Linn Linn Linn Linn Linn Linn Linn He recalled an interview with this magazine in 2011. Controversy around pipes and slides. ” Pointing to pieces of chemically treated paper, her husband said, “The light bulb was on.”
They face two challenges. First, it is necessary for diabetics to check only the type of sugar in their urine. Second, the chemicals they wanted to use were unstable, so they had to find ways to react to light, temperature, and air.
The first problem was easily solved using a recently modified enzyme that responds easily to glucose only. To stabilize the chemicals, Freds experimented with rubber cement, potato flour, varnish, Paris plaster, and egg albumin before placing it on the gelatine, which is best seen.
She and her husband, Mrs. Free, have written two books on urinalysis. She later returned to school at the age of 55, graduating from Central University of Michigan in 1978 with a Master’s Degree in Clinical Laboratory.
Before retiring in 1982, Miles became director of clinical laboratory responses and later director of marketing services at the research unit. The company was then occupied by Bayer. She was elected president American Chemical Society Linn 1993 In 2009, she was awarded the National Technology and Innovation Medal by President Barack Obama. 2011 National Women’s Hall For her role in developing dip-and-reading experiments in Seneca readalls Te, NY.
Alfred Free Linn She died in 2000. In addition to Eric, Mrs. Free had two other sons, Kurt and Jack. Three daughters, Bonnie Gris, Nina Lowjoi and Penny Maloni, stepdaughter, Charles; Two stepchildren, Barbara Free and Jane Linderman; 17 grandchildren; And nine grandchildren.
Mile Laboratories has launched a dip-and-reading glucose test, along with several other tests designed to detect protein, blood and other metabolic, kidney and liver disorders. “They certainly showed their pigs during the investigation and that’s all wrong,” Friff said in a note. He was the one who pushed the diagnostics. ”
Not all were soft ships. Several years after the dip-and-reading experiment began, Miles moved to another room, citing anti-relative policy. But two years later, after a change of government, she moved to her husband’s room.
“Breaking up with a group like this can be detrimental to productivity in the laboratory,” says Fried.
