What can a chemist do?
A chemist is a scientist who researches chemical substances, performs experiments with the properties of chemical substances, measures the effects of chemical compounds in various situations, and studies inter-chemical reactions.
What is Clinistix used for?
Clinistix is a well-known example of a diagnostic reagent strip using an enzyme. They are used to test for the presence of glucose in urine and the mechanism of action involves the enzyme glucose oxidase.
How do Clinistix work?
We can use a special test sticks called Clinistix to test for glucose. The sticks contain two enzymes. The first of these, glucose oxidase, speeds the reaction between glucose (in the test liquid) and oxygen (in the air). This reaction produces gluconic acid and hydrogen peroxide.
Is glucose a reducing sugar?
All monosaccharides are reducing sugars. Glucose, fructose, and galactose are monosaccharides and are all reducing sugars.
How is GTT done?
A glucose tolerance test requires that you fast for 8 to 12 hours (overnight) before the first blood sample is drawn. You will then be given a liquid containing 75 grams of glucose to drink (or 1.75 gram of glucose per kilogram of body weight if you are a child, up to a maximum of 75 grams).
Can you fail the 1 hour glucose test and pass the 3 hour?
Odds of passing The truth about this test is that the one-hour test is pretty easy to “fail,” and many people do! They make the threshold low enough so that they catch anyone who could be having an issue, just in case. The levels on the three-hour test are much more reasonable and easier to meet.
What happens if GTT is positive?
If a patient tests positive for this screening, a glucose tolerance test (GTT) is needed. A GTT is a longer more definitive test that will tell a patient definitively whether or not she has gestational diabetes.
What is considered failing the 3 hour glucose test?
If a patient has two or more abnormal values during the three-hour test, then the test overall is considered abnormal. Your doctor will likely diagnose you with gestational diabetes if you fail the three-hour test.
How do you pass the 3 hour glucose test?
Yes, you can drink water during the 3-hour glucose tolerance test. 3 hours is a long time to not eat or drink anything, especially if you were already fasting for at least 8 hours first. But DO NOT eat or drink anything else. Otherwise, your blood sugar levels will be even higher.
What are the warning signs of gestational diabetes?
Warning Signs of Gestational Diabetes

Does gestational diabetes make baby more active?
Some mothers find a change in movements once they start the gestational diabetes diet and reduce their sugar and carb intake. Others mention reduced movements when having hypos (low blood sugar levels) and increased movements when they have hypers (high blood sugar levels).
Can you get rid of gestational diabetes during pregnancy?
If you’re a pregnant woman who never had any sort of diabetes before you became pregnant, and developed high blood sugar only after becoming pregnant (gestational diabetes), you can safely eliminate it all by yourself within two to three weeks.
What happens to baby if mother is diabetic?
This can affect the baby and mother during pregnancy, at the time of birth, and after birth. Infants of diabetic mothers (IDM) are often larger than other babies, especially if diabetes is not well-controlled. This may make vaginal birth harder and may increase the risk for nerve injuries and other trauma during birth.
What happens to baby when blood sugar is too high?
Higher than normal blood sugar in mothers can cause their babies to grow too large. Very large babies — those who weigh 9 pounds or more — are more likely to become wedged in the birth canal, have birth injuries or need a C-section birth.
Can diabetic mother give birth normal child?
If you are healthy and your diabetes is well controlled when you become pregnant, you have a good chance of having a normal pregnancy and birth. Diabetes that is not well controlled during pregnancy can affect your health long-term and can also be risky for your baby.
