The anti -sulin antibody exam is done to see if your body has produced antibodies against insulin.
Antibodies are proteins that the body produces to protect itself when it detects anything "external", such as a virus or a transplanted organ.
way in which the exam is carried out
Preparation for the exam : Special preparation is not needed.
what you feel during the exam
When the needle is introduced to extract the blood, some people feel moderate pain;Others only feel a puncture or feeling of bite.Subsequently, there may be some pulsatile sensation or a mild hematoma, which soon disappear.
reasons why the exam is carried out
This exam can be done if:
- It has or is at risk of type 1 diabetes
- It would seem to have an allergic reaction to insulin
- Insulin no longer seems to control your diabetes
Normal results : Normally, there are no antibodies against insulin in your blood.
The ranges of normal values may vary slightly between different laboratories.Some laboratories use different measurements or analyze different samples.Talk to your medical care provider about the meaning of the specific results of your exam.
Meaning of abnormal results
If you have IgG and IGM antibodies against insulin, your body reacts to it as if it were something strange.This occurs because the antibody prevents insulin from working properly in cells.Consequently, blood sugar can be unusually high.
Antibodies can also prolong the effect of insulin by releasing something from it long after food has been absorbed.This can be at risk of hypoglycemia.
If the exam shows high levels of the IGE antibody against insulin, your body has developed an allergic response to insulin.This could put it at risk of severe skin reactions where insulin injects.It can also develop more serious reactions that affect blood pressure or breathing.
Other medications, such as antihistamines or injectable steroids in low doses, can help decrease reaction.In the event that the reactions have been serious, a treatment process called desensitization may be required.
risks
The veins and arteries vary in the size of a patient and another and from one side of the body to another, which is why obtaining a blood sample of some people can be more difficult than others.
Other risks of blood extraction are slight, but may include:
- Excessive bleeding
- Fainting or feeling of dizziness
- Hematoma (accumulation of blood under the skin)
- Infection (a slight risk every time the skin break is presented)
- Alternative names
- Antibodies against insulin - serum;Exam for anti -sulin antibodies;Insulin resistance - insulin antibodies;Diabetes - Antibodies against insulin
