Digest Check-up :
Gut Health Blood Test
with Nutritionist
in Zurich & Geneva

Do you feel like your gut is running the show? Bloating after every meal, unpredictable digestion, low mood or anxiety, chronic skin flare-ups, or recurring sinusitis that no one seems to be able to explain. These are not just inconveniences. They are signals. Your body is telling you something deeper is off, and the answer is almost always measurable through a targeted blood test and microbiome analysis.

Understanding the gut

Understanding the gut and why standard tests miss the full picture

Most people with digestive issues have been told their results are within normal range. But conventional blood tests are not designed to look at gut health specifically. They check the obvious, and miss the subtle. Chronic bloating, food sensitivities, abdominal pain, constipation or diarrhoea, excess gas, and inflammatory skin conditions all have measurable biological roots. The Digest Check-up has been designed to find the root cause of your daily discomfort.

Your gut is directly connected to your immune function, your skin, your mood, and your energy levels. When something goes wrong in the gut, the consequences are felt throughout the entire body. A targeted gut health blood test combined with a food sensitivity assessment gives you and your nutritionist the precise data needed to act, not just observe.

The blood panel

What does our Digest Check-up examine?

13 biomarkers targeting the most common and most overlooked biological drivers of digestive symptoms — plus a full microbiome analysis.

Thyroid function (TSH, Free T3 & Free T4) +

An underactive thyroid slows every digestive process in the body, causing constipation, bloating, and sluggish bowel movements that no amount of dietary adjustment will fix. Thyroid dysfunction is one of the most frequently overlooked causes of chronic digestive discomfort, and it is invisible without a blood test.

Vitamins D & A +

Beide Vitamine spielen eine entscheidende Rolle bei der Aufrechterhaltung der Integrität der Darmschleimhaut und der Regulierung von Immunreaktionen. Ein Mangel an einem der beiden Vitamine schwächt die Darmbarriere – ein Zustand, der manchmal als „Leaky Gut“ bezeichnet wird –, wodurch Entzündungsmoleküle in den Blutkreislauf gelangen und Reaktionen weit entfernt vom Darm selbst auslösen können, darunter Hauterkrankungen und wiederkehrende Infektionen.

Iron & Ferritin +

Iron deficiency is closely linked to digestive dysfunction. Poor iron absorption often signals a problem in the small intestine specifically, and it frequently accompanies conditions involving gut inflammation or impaired nutrient uptake. Low ferritin, even when iron levels appear normal, is a sensitive early warning sign.

Zinc +

Zink ist für die kontinuierliche Reparatur und Regeneration der Darmschleimhaut unerlässlich. Bei Menschen mit chronischen Verdauungsbeschwerden, Reflux, Nahrungsmittelunverträglichkeiten und wiederkehrenden Hauterkrankungen wie Akne und Ekzemen lassen sich durchweg niedrige Zinkspiegel feststellen. Im Rahmen einer Standard-Blutuntersuchung wird dieser Wert jedoch selten gemessen.

Liver function (ASAT, ALAT, GGT) +

Die Leber produziert Galle, die für die Fettverdauung und die Aufnahme fettlöslicher Vitamine unerlässlich ist. Eine eingeschränkte Leberfunktion stört diesen Prozess und führt zu Blähungen, Völlegefühl nach dem Essen und einer gestörten Fettverwertung. Die Werte der Leberenzyme sind sensible Frühindikatoren für metabolischen Stress, der in direktem Zusammenhang mit der Darmfunktion steht.

HbA1c +

Chronically elevated blood sugar disrupts gut motility and the balance of intestinal bacteria. A diet high in refined carbohydrates is one of the primary drivers of dysbiosis, the imbalance of gut bacteria that causes many of the symptoms associated with irritable bowel syndrome and food sensitivities. HbA1c provides a reliable 3-month average of your blood glucose levels.

Vitamin B12 (Holotranscobalamin, active form) +

Most labs measure total B12, which includes both active and inactive forms. Holotranscobalamin measures only the active, bioavailable form, making it a significantly more sensitive early indicator of deficiency. B12 is essential for the health of the intestinal mucosa and the nervous system that governs gut motility.

High-sensitivity CRP (hsCRP) +

Standard CRP is designed to detect acute infection or injury. High-sensitivity CRP is a different measurement entirely. It detects low-grade, silent chronic inflammation. It is one of the most clinically valuable markers in the Digest Check-up.

Microbiome analysis +

Über die Blutuntersuchung hinaus erfasst unsere Mikrobiomanalyse die Vielfalt und das Gleichgewicht Ihrer Darmbakterien und identifiziert Dysbiose, bakterielle Überwucherung oder einen Mangel an wichtigen Bakterienstämmen, die sich direkt auf die Verdauung, das Immunsystem und sogar die psychische Gesundheit auswirken. Das Darmmikrobiom wird von Forschern zunehmend als zweites Gehirn bezeichnet. Wenn es aus dem Gleichgewicht gerät, sind die Auswirkungen überall spürbar.

The blood test comes first.
The consultation follows.

Every Digest Check-up begins with your blood draw and microbiome sampling — the gut health blood test at Labology Zurich or Geneva, and the microbiome kit you complete at home. This is where the objective picture of your biology is captured.

Once your results are back, Elodie reviews them with you and builds your personalised nutrition plan — food choices, supplement recommendations, and lifestyle adjustments based on what your biology specifically shows.

Fragen

Frequently
asked
questions

Warum sollte man einen Bluttest zur Darmgesundheit mit einer Mikrobiomanalyse kombinieren?
Blood markers tell you about inflammation, nutrient absorption, and organ function. The microbiome analysis reveals the state of your gut bacteria. The two pieces of information together give a complete picture that neither can provide alone. Blood markers can show that inflammation is present. The microbiome analysis can show exactly which bacterial imbalances are driving it. For anyone dealing with chronic digestive issues or food sensitivities in Zurich or Geneva, combining both is the most effective diagnostic approach available outside of a hospital setting.
Was ist eine chronische Entzündung und wie wirkt sie sich auf die Verdauung aus?
Low-grade inflammation is a silent, persistent immune response that produces no fever, no acute pain, and no obvious symptoms, but steadily damages tissues over time. In the gut, it weakens the intestinal lining, disrupts bacterial balance, and drives symptoms like bloating, abdominal pain and excess gas, food sensitivities, skin flare-ups, and recurring sinusitis. The high-sensitivity CRP test is the only way to detect it reliably through a blood test. Our nutritionist then uses this information to recommend targeted dietary changes aimed at reducing systemic inflammation.
Muss ich vor der Magen-Darm-Untersuchung nüchtern sein?
Yes, we recommend fasting for 8 to 12 hours before your blood draw. This ensures accurate readings for HbA1c, liver function markers, and iron studies. Water is allowed. The microbiome analysis uses a separate stool sample kit that you complete at home — no fasting required for that part.
Wie lange dauert die Mikrobiomanalyse?
Die Ergebnisse der Blutuntersuchung liegen innerhalb von 3 bis 5 Tagen vor. Die Mikrobiomanalyse dauert bis zu 15 Tage ab dem Zeitpunkt, an dem das Labor Ihre Probe erhält. Unser Team benachrichtigt Sie per E-Mail, sobald alle Ihre Ergebnisse auf der Kiro-Plattform verfügbar sind, und anschließend kann Ihr Beratungstermin mit der Ernährungsberaterin Elodie vereinbart werden.
Can the consultation with Elodie be done remotely?
Yes. The consultation with Elodie can be conducted by video call or in person at Labology Zurich. The blood draw always takes place at one of our clinics — Zurich or Geneva. The microbiome kit is used at home, wherever you are.
