To determine helminthiosis, and the truth, the study of stool is more often used. But this does not mean that a blood test for helminths is ineffective. In some cases, it alone helps to diagnose the disease. In this case, scrapings can not show the presence of parasites.
How and when to take a blood test for helminths?
It is not always necessary to carry out the research if there are suspicions of the presence of the disease - headaches, itching in the anal area, the appearance of cracks on the heels, frequent colds , immunity disorders, teeth grinding in a dream. For some groups of patients, analyzes are indicated for prophylaxis. These groups include:
- people who often come into contact with animals;
- health workers;
- employees of schools and kindergartens;
- people living in areas with an increased risk of infection;
- cooks and employees of different dining rooms, restaurants, cafes.
In addition, schoolchildren, pupils of kindergartens and universities should pass a blood test for helminths.
Preparation for the survey is required, but it is not difficult. It is advisable to take tests not earlier than two weeks after stopping any medications. Eight hours before the procedure, you should stop eating food and water. And two days before the study will have to remove from the diet salty, fried, spicy, fizzy.
Explanation of the blood test for helminths
Detailed explanations can be obtained only from a specialist. But you can also understand the main results of the survey yourself. Processing of the test material takes up to five days, but in most cases the answer is given on the second day.
If there are no antibodies to helminths in the blood test, then there is no infection. With positive results, the answer indicates the type of parasites and their approximate number. Patients with borderline results are given a second examination.
