Brief Summary
This is an observational and exploratory study. Participants will be asked for a blood collection and a 24- hour collection of urine. The indol profile and levels of catecholamine and metabolites in PRP, as well as in 24- hour collection of urine will be measured with LC-MS/MS and analyzed.

Patients
Patients are asked for a vena punction and urine collection, if not already done because of medical care.
Interventions
Eligibility Criteria
Patients with foregut NET, patients with a midgut and/or hindgut NET, and healthy volunteers. All patients will be included in one of the groups by a dedicated NET doctor based on a combination of physical symptoms and signs, laboratory values, imaging and histology.
You may qualify if:
- written informed consent
- age above 18 years
- histologically proven NET, with or without treatment for the NET
- a diagnosis made by a dedicated NET specialist based on a combination of physical symptoms and signs, imaging and laboratory values.
- \- Matching in age (plus or minus 3 years) and sex with one of the included NET patients.
- Data of healthy subjects could also be used from the SERT-study, if the subject meets the criteria mentioned above.
You may not qualify if:
- Use of drugs or food supplements that interact with the serotonin-metabolism; all serotonin re-uptake inhibitors, psychotrophic drugs, (other antidepressants; tricyclic antidepressants, MAO-inhibitors, mirtazapin, bupropion, venlafaxin, duloxetin, anxiolytic, antipsychotic and anticonvulsive drugs).
- Drug abuse in the last 8 weeks.
- Use of ≥ 14 alcoholic consumptions a week for women.
- Use of ≥ 21 alcoholic consumptions a week for men.
- Having a neuroendocrine tumor or neuroendocrine carcinoma from any grade and location in present or in history.
- Having a malignancy.
- Having an auto-immune disease.
- Having an infection.
- Having renal impairment.
- Use of interferon.
