Preparation for laboratory analysis

To ensure maximum accuracy and reliability of the results, it is necessary to strictly adhere to the established rules of preparation for the upcoming laboratory analysis. The quality of preparation for test largely determines the standardization of research technology, and thus the quality of the results obtained. 

            How to prepare for blood donation.        

            An important condition for laboratory analysis is blood donation on an empty stomach. This means that the interval between the last meal and blood draw should be 12 hours.

            It is necessary to exclude fatty foods, fried foods and alcohol from the diet 1-2 days before any analysis.

            When examining the hormonal status of women of reproductive age (from about 12-13 years and before the onset of menopause) should pay special attention to the need to strictly adhere to the recommendations of the attending physician about the day of the menstrual cycle, in which the blood should be taken.

            The results of analysis may be influenced by taking medications (for example: antibiotics, immunosuppressive, chemotherapeutic, hormonal drugs, anticoagulants, and others). If you are taking medications, be sure to inform your doctor about this.

           

            How to prepare for urine donation:

            Common urine test.Before collecting urine, hygienic toilet of the external genitalia should be performed. Only the morning portion of urine is collected immediately after sleep. 100 ml is delivered to the laboratory in a clean container.

            Urine test according to Nechiporenko.The toilet of the external genitalia is performed as before the common urine test, after which the average portion of the first morning urine is collected in a clean bowl with a volume of 100 ml.

           

            How to prepare for taking material from the urogenital tract:

·         Before doing the test, do not take alcohol for three days and refrain from sexual activity.

· Two hours before sampling the material, try not to urinate.

·         Exclude the use of local medicines.

· Two weeks in advance you should stop taking antibiotics if this type of treatment has taken place.

           

            How is blood draw from a vein for test?

            What is a hematoma and how to avoid it?

            Dear patients of the OLYMP CDL, we draw your attention:

Venous blood draw for analysis using vacuum closed systems. The vacuum blood draw system is similar to a syringe using a pressure drop instead of a piston movement due to the vacuum in the test-tube.

            A needle will be inserted into the vein and it is possible that immediately during the puncture, you may experience a brief slight pain sensation, which will disappear immediately.

            After blood draw, the needle will be removed, and an alcohol cloth will be applied to the puncture site until the separation of blood drops is completely stopped.

            Extremely rarely, after blood draw at the puncture site, a hematoma (bruise) may occur - this depends on the individual physiological and anatomical characteristics of the human body. This type of hematoma is not particularly dangerous.

To prevent it from appearing, it is necessary to clearly follow the advice of the medical staff blood draw for analysis - press an alcohol napkin with your index finger and keep your arm bent at the elbow for 5-10 minutes. If a hematoma does occur, we recommend using semi-alcoholic compresses or absorbable ointments compresses.                                                             

            Individual vacuum systems for blood draw

            The use of vacuum closed systems for blood draw from a vein is as convenient as possible for the patient and the specialist, it is safe due to the exclusion of contact of the patient's blood with the environment.

            The system ensures the most accurate compliance with the rules of the preanalytical stage of laboratory analysis, significantly reducing the possibility of delivery an erroneous result. The variety of system components makes it convenient and safe to take blood for any type of laboratory test.      

            The vacuum blood draw system is similar to a syringe using a pressure drop instead of a piston movement due to the vacuum in the test-tube. Blood taken for serum or plasma is centrifuged directly in the same test-tube using a separating gel that separates the serum from the clot, ensuring long-term storage of the biomaterial without deterioration of quality.

            Advantages of blood draw using vacuum systems:

·         The ability of blood draw into two or more test-tubes in a very short period of time and without reinserting the needle into the vein.

· The speed of blood draw (5-10 seconds).

·         Maximum safety of medical personnel during the blood draw procedure - the design of the systems completely excludes contact of the patient's blood with the environment.

·         The most accurate observance of the blood-anticoagulant ratio.

·         Simplicity and reliability of marking and transportation of samples.

·         The possibility of using a test-tube without opening the lid when working with some automatic analyzers.
