What you really need to know before your appointment
In Quebec, medical sampling plays a central role in health monitoring. Whether it’s for a blood test, a prenatal test, a food intolerance test or a specialized test, these analyses provide essential information on a person’s state of health. Despite their importance, a number of myths persist and can create anxiety or misunderstanding among patients. Some hesitate to make an appointment, while others delay their tests for fear or lack of information.
In this article, the PRELEV clinic demystifies the most common misconceptions about blood sampling, so that you can better understand its usefulness, procedure and importance in the context of prevention and medical follow-up in Quebec.
Blood sampling plays a fundamental role in modern medicine. They can be used to detect abnormalities, confirm a diagnosis or monitor the progress of a condition. According to the Institut national de santé publique du Québec (INSPQ)(1) , laboratory analyses are an essential tool for supporting clinical decisions and improving the quality of care. In fact, several Canadian studies indicate that over 60-70% of medical decisions are based on laboratory results, demonstrating their importance in our healthcare system.
In a context where prevention is increasingly valued, sampling also enables early intervention, often even before symptoms appear. This is particularly true for certain chronic or silent conditions, such as diabetes, dyslipidemia or certain blood anomalies.
One of the most common concerns is the pain associated with blood sampling. In reality, today’s techniques enable blood sampling and other analyses to be carried out quickly and generally well-tolerated. Healthcare professionals are trained to minimize discomfort and adapt their approach to each individual patient. In most cases, the sensation is brief, comparable to a slight pinch.
With the evolution of practices and equipment, the patient experience has greatly improved in recent years. Specialized clinics, such as PRELEV, also focus on support and communication to reassure patients, especially children and the anxious.
Another common misconception is that all sampling requires an empty stomach. This belief is inaccurate. In fact, some analyses, such as those relating to blood sugar (sometimes) or cholesterol, do require fasting, while others, such as those relating to blood sugar (sometimes) or cholesterol, do not. many others can be performed without any special preparation. Water is always tolerated when you are fasting for blood sampling. In all cases, our team will advise you of the conditions to be met prior to any appointment for blood sampling.
Many patients believe that results always take several weeks to become available. However, this is not the case for most analyses. Turnaround times vary according to the type of test performed. A routine blood test may be available within a few days, while some specialized or prenatal tests may take a little longer. For example, non-invasive prenatal tests such as NIPT, including Verifi or Harmony, generally take from a few to ten working days. This is due to the complexity of fetal DNA analysis.
Thanks to advances in laboratory technology, results can now be obtained more quickly than ever before, helping to reduce the anxiety associated with waiting. At PRELEV, our team will let you know how long it will take to receive your samples.
Please note We do not follow up on blood tests.
Non-invasive prenatal tests represent a major advance in pregnancy monitoring. They enable the detection of certain chromosomal abnormalities from a simple blood sample taken from the mother. According to data published by the Society of Obstetricians and Gynaecologists of Canada (SOGC)(3), these tests have a very high detection rate for certain conditions, notably trisomy 21.
It is important to remember, however, that these tests are screening tools, not diagnostic tools. They can be used to assess a risk, but may need to be followed up by additional tests if a result requires further investigation.

Food intolerance tests are also part of the services offered in the sampling clinic, and often raise questions. Although they do not replace a full medical evaluation, they can help to better understand certain digestive symptoms or food-related discomforts. In many cases, these tests can help guide dietary adjustments and improve quality of life. As with any test, results must be interpreted in a global context, taking into account the patient’s symptoms and medical history.
At PRELEV, we offer both in-branch and in-home food intolerance testing. Contact us to find out which profile would be best suited to your condition.
It’s a mistake to think that sampling is only necessary when you’re ill. On the contrary, they play a central role in prevention. In fact, the Ministère de la Santé et des Services sociaux du Québec (MSSS) encourages regular screening and follow-up to prevent certain diseases and limit their complications. Samples are taken to monitor important parameters such as blood sugar, cholesterol and certain deficiencies. In this way, they help to maintain good health and to intervene rapidly in the event of any abnormality.
Blood sampling is an essential, reliable and safe tool that contributes directly to the quality of care. Although they may give rise to some concern, technological advances and the expertise of our professionals mean that today we can offer a simple, rapid and reassuring experience.
At PRELEV, our team is with you every step of the way to offer you a service tailored to your needs, whether for general sampling, prenatal testing, food intolerance testing or specialized examinations. Our clinics are accessible to provide you with professional and humane care.
