====== Hair sample analyses (external) ======
=== !!PAGE UNDER CONSTRUCTION!! ===

This page provides an overview of additional hair analyses performed at the request of external research groups. These analyses use [[hair samples]] collected during the [[2A|second assessment]], which were subsequently stored in the Lifelines biobank for future analyses. They are complementary to the [[blood analyses|standard blood analyses]] and [[urine analyses|standard urine analyses]] performed as part of the regular assessment program. \\
In addition to the external hair analyses, results from [[blood_analyses_ext|blood analyses by external researchers]] and [[urine_analyses_ext|urine analyses by external researchers]] are also available.\\

===== Methods =====
The analyses are often performed by external laboratories, using samples from participants selected by the research group according to project-specific criteria. As a result, participant selection, sample type, laboratory methods and assessment rounds may differ between projects. Results should be interpreted in the context of the selection criteria and methods described for each project.

===== Study overview =====
The table below provides you with the most relevant points for each project. Details of the available variables are provided below.

It is important to note that the assessment rounds indicate when the urine samples were collected, rather than when the laboratory analyses were performed. While FDI refers to form description of instrument or method.
