Recommendations for how to prepare for blood test:
Avoid drinking or eating anything for 8-12 hours before the test. You may drink only water.
You should not eat 3 hours before the clinical blood test.
Eat less fatty and fried food, and avoid alcohol 1-2 days prior to the test.
Don’t smoke 1 hour prior to the test.
Enzyme and hormone levels vary depending on the time of day, so these tests should be performed before 10 a.m. unless your doctor indicates otherwise.
Avoid any physical activity and stress prior to your blood test. It is recommended that you calm down and relax for 10-15 minutes and think about nothing during the withdrawal.
If you are planning to start using medication, perform tests before or after treatment, and no sooner than 10-14 days post-treatment. If you are taking any medication, tell your doctor or laboratory specialist.
Blood testing is not recommended after massage therapy, reflexotherapy or physiotherapy.
Women’s hormones fluctuate during the menstrual cycle and these fluctuations can influence the results of hormonal testing. For this reason, during preparation for a sex hormone test, it is necessary to indicate the cycle phase and follow the doctor’s recommendations on which cycle day to choose for testing.
When testing the blood for 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 the test in 3-5 days. It is best to perform infection tests 10-14 days after the onset of disease, when antibody production is the most active.
