General instructions before a venous blood sample collection

On the day before the test, avoid increased physical activity and intense physical exercise
In the afternoon and evening before the test, avoid a fatty diet
Unless instructed otherwise by your physician, samples are taken on empty stomach
In the morning before the test, drink approximately 1/4 l of water or plain tea
If you are allergic to disinfectants or certain types of sticking plaster, please notify the lab personnel without delay
If there is a risk you might faint during the blood collection, please notify lab personnel to prevent potential injuries, the sample can be taken while you are lying down
You may eat once the sample collection is finished (diabetic patients in particular should take food with them and observe their usual daily routine as soon as possible afterwards)
Patients should bring their health insurance card for data verification
Blood samples are taken based on a request form filled out by your physician. Sample collections without a request form are only possible with a direct payment.

Unless specified otherwise by the physician, tests are always performed on the first urine of the morning
You should avoid excessive liquid intake during the night to prevent dilution of the urine
The patient is advised to wash their genitals before collecting their urine (to avoid false positive bacteriuria)
The volume should be approximately 10 ml
Women should take a urine sample when not on their period
A sterile plastic test-tube, or a special sample collection vessel provided by the physician or the lab, is required for bacteriological analysis of urine (samples delivered in other vessels will not be accepted for analysis).
For biochemical analysis, urine samples may be delivered in other types of vessels, but they must be clean, dry and free from the residues of the original content (such as medicines, chemicals) prior to collecting a sample. A test-tube may be picked up at the lab any time during its opening hours.
Please label the test-tube or other vessel with your name and health insurance number
The sample should be delivered for analysis preferably within 1 hour and no later than 2 hours after urination

The collection vessel needs to be thoroughly clean and free from any detergent residue
In the morning (usually at 6:00 a.m.) urinate for the last time and begin to collect samples afterwards
Keep the vessel containing the urine in a cool and dark place out of direct light
Follow your usual diet and drink around 2 litres of liquids during the collection period
After 24 hours (i.e. the following day at the same time in the morning, e.g. at 6:00 a.m.) urinate into the vessel for the last time, shake the contents to mix well. You can either deliver the entire contents of the vessel or just a sample. If you plan to only bring a sample, you must measure the exact total volume of the urine you collected.
In the request form, please indicate the collection period, your weight and height, and the total amount of urine (if you are taking a small sample)

Analysis can only be performed if all of the instructions are strictly observed!

Avoid increased physical activity 2 days before the sample collection
Arrive at the lab before 8:00 a.m. and report to the staff
Come to the lab on empty stomach (ideally, do not eat 8 hours before the test, i.e. after midnight) and only drink unsugared water (ca 1/4 l)
The test takes approximately 2 hours
You will be asked to provide a blood sample first
After that you’ll drink a diluted glucose solution over a period of 5 to 10 minutes (for OGTT, this is 75g of glucose dissolved in 500 ml of water or very weak tea)
After ingesting the solution, you will be asked to sit in the waiting room. Blood samples will be taken 60 and 120 minutes after your exposure to the glucose
You must not eat, drink smoke or leave the waiting room in between the blood samples (considered the duration of the test) so please bring something to keep you occupied, such as a book.
