Blood Sample Collection
- It is recommended not to eat 8-12 hours prior to a blood test. It is important to remember that juice, tea, and coffee, especially sweetened, are also considered food. One is only allowed to drink water
- Patient should not eat 3 hours prior to general blood test
- 1-2 days prior to the test it is recommended to eat less fat and fried food, and avoid alcohol;
- Do not smoke for one hour prior to the test
- The levels of enzymes and hormones might vary at different times of day, therefore these tests should be performed before 10 a.m.
- It is recommended to avoid physical load (sports) and stress before the blood test, to calm down and rest for at least 10-15 minutes
- If you are planning to start using medications, perform tests before or after treatment, no sooner than 10-14 days post-treatment. When establishing the efficacy of a drug, blood is tested in 14-21 days after using the drug. If you are using medications, be sure to inform your doctor or laboratory specialist about it
- It is not recommended to perform blood tests after roentgenelogic and ultrasound tests, massage, reflexotherapy or physiotherapy procedures
- The results of women hormone tests are influenced by physiological factors related to the menstruation cycle, therefore, during preparation for a sex hormone test, it is necessary to indicate cycle phase and listen to doctor’s recommendations, on which cycle day to perform tests
- Before performing a stress hormone test (ACTH, cortisol, prolactine, etc.) it is important to calm down, ignore side factors during the procedure and relax because stress increases the level of these hormones in blood
- When performing tests regarding infections, it is necessary to take into account the stage of infection development and the state of immunity. A negative test result does not necessarily show that there is no infection. If laboratory test results cause doubts, it is appropriate to repeat them in 3-5 days. It is best to perform infection tests 10-14 days after the onset of disease, when the antibody production is the most active
Urine Sample Collection

- The middle portion of urine for the test is collected (1.Urinate directly into the toilet. 2. Stop urinating 3. Urinate in the container).
- Secure the lid tightly on the container and confirm that your full name and date of birth are on the label
- In order to ensure accurate laboratory test results it is advised to perform them at the same time in the same laboratory.
- Many drugs, including nonprescription medications and supplements, can affect the results of a urinalysis. Before a urinalysis, tell your doctor about any medications, vitamins or other supplements you’re taking.
Magnetic Resonance Imaging (MRI)
- There is little preparation for an MRI exam. Take your daily medications as you normally would, unless instructed otherwise. There are few dietary restrictions for an MRI. For those exams, you will be notified of the requirements.

- If you have claustrophobia, your doctor may prescribe an oral medication for you to take with you for your MRI appointment.
- Please arrive at least 30 minutes prior to your exam and check in with the receptionist. You will need to complete the MRI screening form.
- To eliminate possible MR safety issues, you will be asked to change into a hospital gown.
- A technologist will verify your identification and the requested exam. Your screening form will be reviewed by the technologist in consultation with the radiologist if indicated. If MRI contrast is indicated for the exam, an IV catheter will be inserted in your arm by a nurse or technologist.
- In the event that sedation is needed (such as for claustrophobia), you will be sent home once awake and alert. If you receive sedation, someone must drive you home.
CT Scan
- You will be asked to remove any metallic or other items and ALL jewelry that might interfere with the scan.
- Your CT scan will take about 15 minutes. Certain types of examinations require that intravenous contrast (“x-ray dye”) be administered in order to best evaluate the organ system or disease.
- During the scan you will be lying on a padded table. You may be asked to lie on your stomach, back or side, and to hold your breath or stay very still. You may hear humming noises or feel the table move slowly through the CT scanner.
- If you received contrast, you should drink about five glasses of water to help flush out the contrast that was injected. If the area where the plastic tube (IV tube) was placed inside your vein is red, swollen or sore, you should put a warm, wet towel on the area four times a day for 15-20 minutes. If swelling continues for more than 48 hours, you should call your doctor.
Mammography
