            • Food intake.
            • Physical and emotional overload
            • Alcohol.

            • Physiotherapy, instrumental examinations carried out before the delivery of biomaterials.
            • The phase of the menstrual cycle in women.
            • Time of day when taking blood (there are daily rhythms of human activity and, accordingly, daily fluctuations in many hormonal and biochemical parameters, expressed to a greater or lesser extent for different indicators).

            General rules when preparing for research

            Blood test

            It is advisable to observe the following rules when conducting biochemical, hormonal, hematological tests, complex immunological tests.

            If possible, it is recommended to donate blood in the morning, in the period from 8 to 10 hours, on an empty stomach (at least 8 hours and not more than 10 hours of hunger, drinking water, as usual), avoid food overloads the day before.

            More stringent requirements for the diet are imposed in the following cases:

            • strictly on an empty stomach, after 12-14 hours of fasting, blood should be donated to determine the parameters of the lipid profile (cholesterol, HDL, LDL, triglycerides);
            • the glucose tolerance test is performed in the morning on an empty stomach after at least 12, but not more than 16 hours of fasting.

            If you are taking any medications, you should consult with your doctor about the advisability of conducting a study while taking medications or the possibility of discontinuing the drug before the study, the duration of cancellation is determined by the period of elimination of the drug from the blood.

            Alcohol - Avoid drinking alcohol on the eve of the study.

            Smoking - do not smoke for at least 1 hour before the study.

            Eliminate physical and emotional stress on the eve of the study.

            After arriving at the laboratory, it is recommended to rest (it is better to sit) for 10-20 minutes before taking blood samples.

            It is undesirable to donate blood for laboratory research soon after physiotherapy procedures, instrumental examination and other medical procedures.

            When monitoring laboratory parameters in dynamics, it is recommended to conduct repeated studies under the same conditions: in the same laboratory, donate blood at the same time of day, etc.

            General urine analysis

            The collection of the analysis is carried out in a container for urine analysis.

            On the eve of the test, it is recommended not to eat vegetables and fruits that can change the color of urine (beets, carrots, etc.), do not take diuretics.

            Before collecting urine, it is necessary to make a hygienic toilet for the external genital organs (in the evening, on the eve of the toilet with boiled water and soap, in the morning, just before collection, - toilet with boiled water without detergent).

            Women are advised not to have a urine test during their period.

            Collect approximately 50 ml of morning urine in a container. For the correct study, during the first morning urination, a small amount of urine (the first 1 - 2 seconds) is released into the toilet, and then, without interrupting urination, substitute a container for collecting urine, in which to collect approximately 50 ml of urine.

            Close the container tightly with the screw cap immediately after collecting urine.

            It is necessary to deliver a container with urine to the laboratory within a day (according to the schedule for receiving biomaterial until 9).

            Collection of daily urine for biochemical analysis

            Urine is collected per day.

            The first morning urine sample is removed. All subsequent portions of urine excreted during the day, night and the morning portion of the next day are collected in one container, which is stored in the refrigerator (+4 ... + 8 ° C) during the entire collection time (this is a necessary condition, since at room temperature significantly decreases glucose content).

            At the end of the collection of urine, its volume is measured, the urine is thoroughly shaken and 50-100 ml is poured into a special container in which it will be delivered to the laboratory; - be sure to indicate the volume of daily urine.

            Collection of urine for research according to Nechiporenko

            (revealing a latent inflammatory process)

            • in the morning on an empty stomach, collect at least 10 ml of morning urine taken in the middle of urination in a special laboratory container.

            Collection of urine for research according to Zimnitsky

            (the patient takes into account the amount of liquid drunk per day)

            • after emptying the bladder at 6 o'clock in the morning, every 3 hours during the day, urine is collected in separate containers, which are indicated by the collection time or portion number, a total of 8 portions. 1 portion - from 6.00 to 9.00, 2 portion - from 9.00 to 12.00, 3 portion - from 12.00 to 15.00, 4 portion - from 15.00 to 18.00, 5 portion - from 18.00 to 21.00, 6 portion - from 21.00 to 24.00, 7 portion - from 24.00 to 3.00, portion 8 - from 3.00 to 6.00;
            • all the collected amount of urine in 8 special (signed, indicating the number and time) containers are delivered to the laboratory;
            • be sure to indicate the volume of daily urine.
            • Collection of urine for microbiological examination (urine culture)

              • morning urine is collected in a sterile laboratory container with a lid;
              • the first 15 ml of urine are not used for analysis, the next 5-10 ml are taken;
              • collected urine is delivered to the laboratory within 1.5 - 2 hours after collection;
              • storage of urine in the refrigerator is allowed, but not more than 3-4 hours;
              • collection of urine is carried out before the start of drug treatment; 
              • if it is necessary to assess the effect of the therapy, urine culture is performed at the end of the course of treatment.

              Stool analysis

              The collection of the analysis is carried out in a container for the analysis of feces (with a spatula).

              The material (feces) is collected before starting treatment with antibacterial and chemotherapy drugs. For research, freshly excreted feces are collected.

              3 - 4 days before the study, it is necessary to stop taking laxatives, castor and petroleum jelly, stop the administration of rectal suppositories. The feces obtained after the enema are not used for research.

              Before collecting the analysis, urinate in the toilet, then, by natural defecation, collect the stool in a bed vessel (make sure that no urine gets into). The bedpan is pre-treated with any disinfectant, thoroughly rinsed with running water several times and rinsed with boiling water.

              The feces are collected in a clean, disposable container with a screw cap and a spoon in an amount not exceeding 1/3 of the container's volume. The material is delivered to the laboratory within 3 hours from the moment of collection of the analysis. It is advisable to keep the material in the cold (temperature + 2 + 8) for the specified time. Avoid freezing!

              The container must indicate your surname, initials, date of birth, date and time of collection of the material, the entry must be made in legible handwriting. When taking the material, sterility must be observed. If possible, the collection of material for the study should be carried out before the appointment of antibiotics (if not possible, then only 12 hours after the drug is discontinued).

              Conditions that must be met:

              • freezing is not allowed;
              • long-term storage is not allowed (more than 5 - 6 hours);
              • a loosely closed container is not allowed;
              • biomaterial collected the day before is not subject to research.

              Sputum analysis

              The best time to collect sputum is early in the morning. So it is much more likely to get the sputum accumulated during the night when coughing, and not saliva.

              Sputum collection is carried out strictly on an empty stomach.

              Immediately before collecting sputum, thoroughly brush your teeth, spit out the accumulated saliva and rinse your mouth first with boiled water.

              The material is collected in a clean, dry jar or in a sterile container (bakprint) with a sealed lid.

              If sputum is separated in a meager amount, it is necessary to take expectorants on the eve of collecting the material. You can use aerosol inhalation, provoking an increase in bronchial secretion, or use the inhalation of a hot saline hypertonic solution for 10-20 minutes.

              The container is tightly closed and the sputum is delivered to the laboratory no later than one hour after collection. If it is impossible to deliver the sputum within an hour, then the biomaterial can be stored in a refrigerator at 3-5 ° C for no more than 3 hours before testing.
