Preparation for stool analysis

General recommendations

When collecting biomaterial, it is important to follow the basic rules, regardless of what it is for:

• Before collecting feces, you need to urinate and flush the toilet, then collect after spontaneous bowel movements.
• For selection, you need to stock up on a universal container, with a reliably screwing lid. One sample should contain approximately half a teaspoon or a special spatula attached to the container. It is necessary to select from various parts of the feces, filling the vessel volume by no more than 30%.
• When analyzing for microbiology, the sample is taken in a special, reliably closed sterile container.
• Before collecting feces, you do not need to change your diet or drinking regimen.
• If the patient takes laxatives, sympathomimetics, drugs with enzymes, iron or bismuth, 4 days before the delivery of the material, they should be abandoned. The same should be done if rectal candles are used.
• In cases where sowing on the microflora will be performed, the analysis is taken before the course of antibiotics or chemotherapeutic agents. If you can not cancel the reception, before the analysis you need to pause 12 hours.
• When analyzing for hidden blood, 3 days before delivery, you need to abandon all types of meat, tomatoes, exclude drugs and products that include iron in any form.

When collecting material, you can not use any adapted dishes, including matchboxes or your own cans. When collecting, you should avoid urine or sex secrets.

Features of delivery of analysis

The sample collected at home should be delivered as quickly as possible to a specialized laboratory. The permissible period does not exceed 40 minutes, while it is desirable to ensure a temperature not higher than +4°S.

Contraindications

Certain circumstances hinder the objectivity of the study and lead to a distortion of the result. In this case, the delivery of feces must be abandoned. Such contraindications include:

• Conditions and diseases accompanied by bleeding from the rectum. These include hemorrhoids, severe constipation, bleeding gums, etc.
• For women, the limitation is the period of menstruation.
• If an X-ray of the intestine or stomach was performed, the analysis can be taken no earlier than after 2 days.
• It is strictly forbidden to give feces after an enema.

Preparation for studies on hidden blood

This is one of the fundamental studies that allow you to diagnose various diseases of the gastrointestinal tract, but for its objectivity you need to follow the following rules:

• 3 days before delivery, you need to exclude all products and offal of animal origin, as well as iron-rich vegetables and fruits, for example, spinach, apples, sweet pepper.
• Restrictions on X-rays are the same as in the general rules.
• The chair must be spontaneous without additional stimulation, selection must be made from different areas of the material.

Preparation for scraping for enterobiasis

Biomaterial for enterobiasis is selected with special care. For this, a special test tube and probe are issued. The scraping is taken directly around the anus from the so-called perianal folds.

After waking up in the morning, with the help of circular movements around the anus, a scraping is applied to the probe and placed in a test tube. It is important to take the analysis before carrying out traditional hygiene procedures. The material must be delivered no later than 3 hours after scraping.
