Diagnostic Tests Information

The exact tests performed in our Unit are performed by collecting blood, saliva, urine and feces.
Well-trained scientific staff oversees the procedures, explains and guides patients with clear written instructions.


Blood sampling is done daily from 09:00 a.m. until 21:00 p.m. by experienced blood donors, who take care of the patient’s complete blood sampling, blood storage and transport of the sample to the laboratory.
We ensure that the procedure is properly followed with ISO certifications and we follow protocol in every laboratory test such as blood centrifugation, referral supplementation and proper use of blood sampling tubes.


Salivary cell sampling is painless and is performed by the simple friction of the inner cheek of a cotton swab.
The test detects specific indicators of inflammation, which betray the presence of diseases such as cancer, diabetes and heart failure.


It is a laboratory test performed on a urine sample, which is collected for 24 hours.

  • You will be given a container in which to store the urine.
  • The collection should be started in the morning. Note the time of the first urination.
  • Store the container in a cool place, preferably in the refrigerator.
  • Try to urinate again at the same time, 24 hours after the start time, to complete the collection process. If you can’t, it’s not a problem.
  • Once the collection is complete, transfer the urine container to our Unit.

The 24-hour urine collection will give an absolute estimate of the number of cellular functions and systems of the body (enzymes, catalysts, metabolites, coenzymes, etc.), helping your doctor assess the severity and, in some cases, give information about the prognosis of damage.


Stool sample collection is performed by the patient himself and is usually done in the following ways:

  • Collect stool once
  • Collect 24 hour stool
  • Stool collection after taking a saline cleanser.

The required amount of stool is about 8-10 grams.

The sample is collected in a sterile plastic container tightly closed to prevent leakage.


There are examinations that are performed in Greece and others that are sent to foreign countries, in contracted and specialized diagnostic centers with ISO certification.

The purpose of the IATOR Medical Unit is to ensure the quality and validity of the results, which is done successfully by performing continuous quality controls.
