What is Lysine?

Lysine is an essential amino acid that our body cannot produce itself. It plays a crucial role in the production of proteins, enzymes, and hormones, and is important for the maintenance of skin and the immune system.

Why should you have Lysine measured/tested?

Testing Lysine is useful for people suffering from Rosacea, a chronic skin condition that causes redness and pimples on the face. Lysine may help reduce the symptoms of Rosacea through its role in skin health and immune function.

What does it indicate?

The Lysine test measures the amount of Lysine in the blood. The results can help identify nutritional deficiencies or assess whether Lysine supplementation might be beneficial for the management of Rosacea.

What does a high Lysine level mean?

A high Lysine level may indicate sufficient intake of the amino acid through diet or supplements. It is rarely a sign of problems, but it is important not to consume too much Lysine, as this can lead to side effects such as stomach pain or diarrhea.

What does a low Lysine level mean?

A low Lysine level may indicate a deficiency, which can contribute to skin problems, reduced immune function, and increased susceptibility to infections. In the case of Rosacea, a deficiency can worsen symptoms.

Frequently asked questions

Answers to what people usually want to know.

How does it work from order to result?

After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.

How quickly can I get tested?

Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.

Do I need to book an appointment?

At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.

Do I need to fast before the test?

    That depends on the test. Whether fasting is required, and from what time, is clearly stated in the instructions you receive after ordering. No surprises at the counter.

    When and how do I receive my result?

    It varies per analysis: from same-day to a few working days. Standard values often come back quickly; analyses that go to an external lab can take a bit longer. You get an email with a link to your digital result, including a short explanation per value.

    Where can I go for collection?

    We work with 1,000+ collection points across the Netherlands. After ordering you'll see which locations near you are available and you pick where you'd like to go.
