Taking a blood test for sugar
A referral for the test is issued by the attending physician if the patient has symptoms characteristic of endocrine diseases associated with changes in glucose levels. Indications for the test:
- Sharp weight loss;
- Constant thirst and dry mouth;
- Fatigue;
- Overweight;
- Polyuria;
- Regular symptoms of fungal stomatitis and thrush;
- Presence of diabetes in close relatives.
The test is also mandatory for pregnant women, people with high blood pressure and impaired carbohydrate metabolism. It is worth noting that glucose diagnostics are used not only to confirm or refute diseases, but also to evaluate treatment.
How to take a blood sugar test?
The results of the study directly depend on the food we eat the day before and physical activity. That is why you should take the preparation process seriously and adhere to the following rules:
- Limit physical activity the day before the test;
- Do not eat sweets, confectionery, carbonated water, alcohol, flour products, or chewing gum for 24 hours;
- Blood must be given on an empty stomach (the last meal should be 8 hours before the test);
- In the morning, you can only drink clean water;
- You should also refrain from smoking the day before the test.
The sample itself is taken from a finger. The test takes no more than a few minutes, after which the blood is sent for analysis.
How to lower blood sugar before the test?
Many patients try to lower its content in the body in every possible way before taking a sugar test. They use medications and folk remedies in the form of special diets, herbal decoctions, juices and infusions. However, this is highly undesirable. The fact is that artificially lowering the glucose level will only give a temporary result, but will not get rid of the root of the problem. A distorted analysis picture will only aggravate the situation: the doctor will not be able to prescribe the correct treatment, which means that the patient's health will deteriorate.
General blood test sugar: types
One of the most common methods for determining sugar concentration is a laboratory test. It is carried out in the first half of the day. Blood is taken either from the ring finger or from a vein. The analysis is not only a diagnostic, but also a preventive measure. It is recommended for systemic diseases, as well as general malaise, deterioration in health.
If minor deviations from the norm were detected during the laboratory analysis, additional tests are carried out, including glucose tolerance. The study is carried out by taking several measurements. The first is done on an empty stomach, after which the person is given a sweet solution and the glucose level is measured after 2 hours. This test evaluates the reaction of cells to a large amount of sugar entering the bloodstream. It is necessarily prescribed to pregnant women to detect gestational diabetes, which is dangerous for both the mother and the child.
To determine the type of diabetes, an analysis of the C-peptide level is used. However, such a study has significant contraindications. It cannot be performed on patients with chronic diseases, stroke, heart attack, undergoing treatment or after surgery, childbirth.
The effectiveness of treatment is assessed by measuring glycated hemoglobin. The test shows the concentration of glucose over a period of 1 to 3 months.
Blood sugar test: decoding
- For laboratory testing, the glucose concentration should be within 3.5 - 5.5 mmol / l. If the value increases to 6 mmol / l, a prediabetic state is established. If the indicator reaches over 6 mmol / l, then diabetes mellitus is diagnosed.
- For the glycated hemoglobin test, the normal values are 4 - 8%.
- The sugar tolerance test has its own values: up to 7.9 mmol / l is normal; 7.9 – 11 mmol/l – prediabetes; over 11 mmol/l – diabetes mellitus.
The norms are different for children:
- For infants and babies up to 1 year old, the sugar concentration should be within 2.8 – 4.4 mmol/l.
- For children from 1 to 5 years old, the indicator increases to 3.3 – 5 mmol/l.
Then the norms are similar to adults.
Any deviations from the norms are a reason to contact a therapist. You should not delay treatment and therapy, as this can cause significant health problems in the future.
