Hormones control practically everything – mood, energy, sleep, weight, fertility, and even how quickly we age. It's no wonder that interest in hormone testing has grown significantly in recent years. However, the market today offers several different ways to have your hormones measured, and they differ not only in price but also in what they actually reveal. The two most frequently discussed approaches are classic blood hormone tests and the so-called DUTCH test – an advanced analysis from urine and saliva that promises considerably deeper insight into hormonal health. But how do you make sense of it all, and when is it worth investing in the more expensive option?
Most people first encounter hormone testing at their gynaecologist or GP. They receive a referral for a blood draw and a few days later hold results showing values for oestradiol, progesterone, testosterone, or TSH. This approach works well in many situations – it's accessible, covered by insurance, and doctors have years of experience with it. Nevertheless, it has its limitations, which become apparent precisely when a person suffers from vague complaints that classical results don't reflect at all.

What blood tests actually measure – and what they miss
A blood analysis captures the so-called serum hormone level – its current concentration in the blood at the moment of collection. This is valuable information, but incomplete. Hormones don't act in the body directly in their "raw" form – they undergo complex biochemical transformations, and only their metabolites enter cells and influence their behaviour. Blood tests don't routinely capture these metabolites.
Another factor is time. Hormone levels change dramatically throughout the day and across the monthly cycle. Oestradiol can be completely different in the morning than in the afternoon. Cortisol peaks shortly after waking and declines by evening. A single blood draw therefore represents just one snapshot from a continuous hormonal film. If the doctor happens to catch the "wrong" moment, the result may not reflect what the patient is actually experiencing.
This is precisely where the DUTCH test comes into play. The acronym DUTCH stands for "Dried Urine Test for Comprehensive Hormones" and is a method developed by the American company Precision Analytical. Unlike a one-time blood draw, urine samples are collected at several time points throughout the entire day – typically four to five times. This makes it possible to capture the daily rhythm of hormones, particularly cortisol and DHEA, and map their curve. The result is not a single number, but a comprehensive picture of how the hormonal system functions over the course of the whole day.
Moreover, the DUTCH test measures not only the hormones themselves, but also their metabolic pathways – that is, the routes by which hormones are broken down in the body. This is crucial, for example, with oestrogen, which can be metabolised via either safe or potentially problematic pathways. Research published in the journal Journal of Steroid Biochemistry and Molecular Biology has repeatedly highlighted that the way oestrogen is metabolised plays a role in the risk of developing certain hormonally driven conditions. A blood test simply cannot provide this information.
When a blood test is sufficient and when it falls short
It would be unfair to claim that blood tests are outdated or unnecessary. For a wide range of situations, they are entirely adequate and their simplicity is an advantage. If a doctor needs to confirm a diagnosis of hypothyroidism, check TSH levels, or determine whether a woman has entered menopause, a blood test will fulfil its purpose reliably and inexpensively. Similarly, when monitoring hormone replacement therapy or when there is suspicion of a significant hormonal imbalance – such as polycystic ovary syndrome – blood results provide a solid starting point.
The situation changes, however, for people who suffer from chronic fatigue, sleep disturbances, persistent anxiety, mood swings, or weight problems, while their blood results look "normal." This group of patients is most often left disappointed by the classical approach. They feel unwell, but the results say everything is fine. How is this possible? The problem may lie precisely in what a blood test cannot see – a disrupted cortisol rhythm, unfavourable oestrogen metabolic pathways, or insufficient conversion of hormones into their active forms.
Consider a specific example. A thirty-year-old woman suffers from chronic fatigue, poor sleep, difficulty concentrating, and weight gain despite making efforts to eat healthily. Blood tests show normal values for the thyroid, oestradiol, and cortisol. The doctor finds nothing wrong. However, after performing a DUTCH test, it becomes apparent that her cortisol curve is flat – instead of a healthy morning peak followed by a gradual decline, cortisol remains low and even throughout the day. This is a typical pattern of adrenal exhaustion, which a blood test will not detect because the average daily value may appear normal.
Women experiencing difficulties in the second half of their cycle – irritability, water retention, breast tenderness, poor sleep – are in a similar position. The DUTCH test can show the ratio of oestrogen to progesterone throughout the entire luteal phase, far more precisely than a single blood draw timed to day 21 of the cycle.
The DUTCH test: for whom and under what circumstances
More expensive testing makes sense when the cheaper option fails to provide answers. This is the fundamental principle that should guide every decision about hormone testing. In the Czech Republic, the DUTCH test typically costs between three and six thousand crowns, and health insurers do not routinely cover it. This is not a negligible sum, which is why it's important to know who will genuinely benefit from it.
Those who benefit most include people who:
- suffer from unexplained chronic fatigue or burnout syndrome
- have recurring problems throughout the menstrual cycle despite normal blood results
- are going through perimenopause and want to understand what is actually happening in their bodies
- use hormone replacement therapy and want to verify whether the hormones are being properly absorbed and metabolised
- suspect oestrogen dominance or other hormonal imbalances of a subtler nature
- are monitoring the impact of stress on their hormonal system and want to see concrete data about the cortisol axis
Conversely, for someone who needs a quick overview or is dealing with an acute health problem, a blood test is faster, more accessible, and entirely sufficient. The two approaches are not mutually exclusive – experienced functional doctors and naturopaths often combine them to obtain the most complete picture possible.
It is also important to consider who interprets the results. The DUTCH test generates a detailed report with dozens of values and their interrelationships. Without expert guidance, it can be confusing or even misleading. Ideally, the results should be assessed by a doctor or therapist familiar with functional medicine, integrative gynaecology, or naturopathy. Organisations such as the Institute for Functional Medicine provide training for professionals working with precisely these advanced diagnostic tools.
As American endocrinologist and author of books on hormonal health Dr. Mark Hyman aptly noted: "Normal is not the same as optimal. Your results may be within the reference range and you may still feel terrible." This thought captures the essence of the entire debate – the reference values of blood tests are set for the average population, not for a specific individual with their unique needs.
It is also worth comparing with salivary cortisol analysis, which is sometimes offered as a less expensive alternative to the DUTCH test. Salivary tests are capable of capturing the daily cortisol rhythm in a similar way to the DUTCH test, but they do not provide information about hormonal metabolites or sex hormones to the same extent. For the specific purpose of monitoring the cortisol axis alone, they may be sufficient, but they cannot match the DUTCH test in terms of comprehensiveness.
It is worth noting that hormonal health cannot be separated from lifestyle. Even the most precise test is merely a diagnostic tool – what a person does with the results depends on changes in diet, exercise habits, sleep hygiene, and stress management. Products that support hormonal balance – adaptogens such as ashwagandha or maca, quality magnesium, vitamin D, or omega-3 fatty acids – can be a valuable complement, but they can never replace an understanding of what is actually happening in the body. And this is precisely what a well-chosen diagnostic approach is for.
The decision between a classic blood test and the DUTCH test is therefore not a question of which is "better" in general, but of what question a person is trying to answer. If the goal is quick diagnosis or monitoring of a known condition, a blood test is an efficient and sufficient choice. However, if someone is looking for answers to chronic complaints that have so far remained unexplained, or genuinely wants to understand how their hormonal system functions in all its complexity – then investing in advanced testing makes sense. The body deserves to be understood, not merely roughly measured.
