NAD Test

First register your test kit online, disinfect your fingertip and position the lancet as described. Allow several drops of blood to fall onto the marked areas of the dried-blood card, let the card dry completely and then send it to the laboratory in the enclosed return envelope.

Warm your hands well before collection so that the blood flows more easily, and do not touch the filter area of the card directly with your finger. The blood drops should completely and evenly saturate the marked circles. Allow the card to dry for several hours and only then package it as instructed to help preserve the stability of the NAD markers.

You can generally collect the blood sample at any time of day. Choose a time that reflects your normal daily routine and avoid unusual stressors immediately beforehand, such as very intense physical activity, an acute infection or heavy alcohol consumption, so that the measured NAD status is as representative as possible.

As a rule, you do not necessarily need to stop taking NAD-related supplements because the test is intended to measure your actual current NAD status. However, when you want to document a baseline before starting a new supplementation or treatment strategy, it may be useful to test before starting or after a stable period of use and to take this into account when interpreting the result.

In principle, you can take the test while continuing your medication. Because some medicines can influence energy metabolism and NAD-dependent processes, you should always mention all relevant medication when discussing the findings with a physician or another qualified professional.

Ideally, send your sample on the day it is collected or on the following business day so that transport and storage times remain as short as possible. Dried-blood samples remain stable for a limited period, but they should still be sent promptly to preserve the NAD content as effectively as possible.

Allow the dried-blood card to dry completely, then store it in a dry, dark place at room temperature, protected from direct sunlight. Send the sample as soon as possible, generally within a few days of collection.

The return address is already printed on the enclosed return envelope. Simply package the sample as described and send it through the regular postal service; no additional address information is required.

For returns from outside Germany, follow the enclosed shipping instructions and, where required, declare the sample as a dried-blood sample or a low-risk biological sample. Allow for possible longer transit times and customs checks, and send the sample as soon as possible after collection.

Yes. You can collect the sample together with your physician if they are willing to assist you. However, the test remains an at-home test whose sample is sent to a specialist laboratory.

The NAD test measures the level of NAD (NAD⁺ and NADH) in the dried blood sample, which primarily reflects intracellular NAD status. A lower or higher value can provide an indication of how well your cells are currently supplied with this coenzyme and the state of key processes such as energy production, redox balance and certain repair mechanisms. The specific interpretation is always made in the context of your personal situation.

The results report shows your NAD value or NAD index in relation to reference or comparison ranges and classifies it in easy-to-understand categories. In addition, you receive explanatory information about the function of NAD, possible influencing factors and general, non-therapeutic guidance on which lifestyle areas you may wish to monitor particularly closely in consultation with qualified professionals.

Intracellular NAD tests based on dried blood were specifically developed to make NAD-dependent processes measurable in research and personalized prevention. The combination of a validated dried-blood method and defined evaluation algorithms enables a robust determination of NAD status; however, the test does not replace a medical diagnosis.

When you make targeted changes to your diet, training volume, sleep or NAD-related supplements, repeat testing can show whether your NAD status changes over time. The NAD Test can therefore serve as an objective feedback tool for assessing, together with qualified professionals, whether your measures have measurable effects on cellular energy and longevity-related status.

Once your sample has arrived at the laboratory, analysis usually takes around 3–4 weeks. As soon as the report is complete, you will be notified and can access your results in a secure online area.

Your sample is processed pseudonymously in the laboratory using a sample code, while personal data are managed separately. The digital report is provided through a secure platform, and data processing follows the applicable data-protection and security standards.

Yes. The report contains detailed, easy-to-understand explanations of your NAD measurement and the reference ranges used. You can also discuss your results at any time with your doctor or with specialised longevity and nutrition experts in order to relate them to other findings and your individual situation.

An additional medical consultation after the result is not mandatory as standard. You can discuss the result with your treating physician or book a separate longevity or nutritional consultation in which the findings are explained in detail and possible next steps are discussed.

Additional consultation packages can be booked if desired. During the consultation, your NAD results are placed in the context of your overall health and longevity profile, and practical strategies relating to nutrition, recovery, training and, where appropriate, supplementation are developed with you.

The test is particularly suitable for people who want to understand their cellular energy and longevity status using objective data and monitor changes in lifestyle or NAD-related interventions. Any individual conclusions and measures should always be determined together with medical or nutritional professionals.
