To undergo a blood sampling or a urinalysis It's a fundamental step in monitoring our health. However, small, last-minute doubts often arise in the lab: "Can I drink a glass of water? How should I collect the sample?".
To ensure accurate results, preparation is important as the analysis itself. Here's our practical guide to avoid mistakes.
The most common question: can you drink water before exams?
The short answer is: yes, natural water is allowedUnlike sugary foods and drinks (coffee, tea, juices), which should be absolutely avoided to avoid altering blood sugar and fat levels, water does not interfere with the results of the blood test or those of the urine.
In fact, being well hydrated can make blood sampling easier. easierThe important thing is not to overdo it and drink only still, natural water (a glass is fine).
