world. Physical activity may exert beneficial influence on the cardiovascular system, besides to bring benefits to the lipid metabolism, the increase of the lean mass, and the increase of the basal metabolism. As a response of the physical activity, the concentration of several hormones is altered, as the cortisol. Different specimens are used to determination of concentration of the cortisol, like saliva, urine, blood samples and hair. The aim of this narrative review is to present scientific information about the use of the hair to evaluate the concentration of cortisol in individuals that have performed physical activity.

We provide an overview of hair cortisol research in general and an update on methodological considerations including the incorporation of cortisol into hair, hair growth rates, and sampling procedures, mincing vs. grinding of samples during preparation for extraction, various extraction protocols, and quantification techniques. We compare the clinical utility and application of hair cortisol with traditional methods of measurement while acknowledging the limitations of analysis including variations in hair growth parameters. We explore the value of hair cortisol in cases of Cushing syndrome (particularly Cyclical Cushing), Adrenal insufficiency (including Addison&#39;s disease), therapy monitoring, cardiovascular disease, stress, and mental illness.

However, cortisol levels are subject to variations due to acute stress, the diurnal rhythm and pulsatile secretion. Cortisol measurements in body fluids are not always a reflection of long-term cortisol exposure. The analysis of cortisol in scalp hair is a relatively novel method to measure cumulative cortisol exposure over months up to years. Over the past years, hair cortisol concentrations (HCC) have been examined in association with a large number of somatic and mental health conditions. HCC can be used to evaluate disturbances of the HPA axis, including Cushing&#39;s syndrome, and to evaluate hydrocortisone treatment. Using HCC, retrospective timelines of cortisol exposure can be created, which can be of value in diagnosing cyclic hypercortisolism. HCC have also been shown to increase with psychological stressors, includi...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Clinical applications of cortisol measurements in hair","attachmentId":44137817,"attachmentType":"pdf","work_url":"https://www.academia.edu/23715261/Clinical_applications_of_cortisol_measurements_in_hair","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/23715261/Clinical_applications_of_cortisol_measurements_in_hair"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="5" data-entity-id="70600625" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/70600625/Validity_and_reliability_of_method_used_to_analyse_hair_cortisol_concentration">Validity and reliability of method used to analyse hair cortisol concentration</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="185230481" href="https://tudublin.academia.edu/JordanReid">Jordan Reid</a></div><p class="ds-related-work--metadata ds2-5-body-xs">F1000Research</p><p class="ds-related-work--abstract ds2-5-body-sm">Hair cortisol analysis is a method of analysing the stress hormone cortisol that offers great potential for helping researchers understand the long-term impact of stress and distress on the body. Hair analysis not only provides an excellent method of studying the average production of cortisol over weeks and months, but also the potential to understand cortisol levels several months before the hair was collected. Whilst research with hair samples for cortisol analysis is a fast-developing field, there has been less analysis of the methods used to analyse hair cortisol. We report two studies where the novel hair analysis method developed at the Anglia Ruskin university (ARU) Biomarker Laboratory was tested for reliability and validity. In study 1, 32 participants provided hair samples for an examination of the reproducibility of the hair cortisol analysis method.

Hair samples were obtained from 286 individuals. After cortisol extraction, samples were measured in a Siemens Immulite 2000 (Gwynedd, UK) automated chemoluminiscent immunoassay analyzer. Normal reference values were obtained from hair cortisol levels measured in 213 healthy individuals with low levels of stress. Hair cortisol concentration median was 55 pg/mg hair (2.5–97.5 percentile (40–128)) in healthy individuals with low levels of stress and 250 pg/mg hair (range 182–520) in stressed individuals. No significant differences were observed in hair cortisol levels between subjects with and without dye (40 (40–107) and 40 (40–155) pg/mg hair, respectively; p = 0.128).

One can apply immunoassay as well as gas and liquid chromatography with various types of detection, depending on the available equipment and the experience of the analyst. The question is how the methods are interchangeable between themselves. Doubts were reported having compared immunoassays and chromatography-mass spectrometry, but there are scarce data on chromatographic methods with detection types other than mass spectrometry. Methods Here, we present the detailed comparison of two liquid chromatographic methods for the determination of free urinary cortisol and cortisone: one with fluorescence detection (high-performance liquid chromatography [HPLC-FLD]) and the other with tandem mass spectrometry (HPLC-MS/MS). The comparison was made with 199 human urine samples. The data analysis included Passing–Bablok and Deming regression, Bland–Altman test, Wilcoxon test, mountain plot and Lin’s concordance correl...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"High-performance liquid chromatography methods for the analysis of endogenous cortisol and cortisone in human urine: comparison of mass spectrometry and fluorescence detection","attachmentId":88694185,"attachmentType":"pdf","work_url":"https://www.academia.edu/83304197/High_performance_liquid_chromatography_methods_for_the_analysis_of_endogenous_cortisol_and_cortisone_in_human_urine_comparison_of_mass_spectrometry_and_fluorescence_detection","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/83304197/High_performance_liquid_chromatography_methods_for_the_analysis_of_endogenous_cortisol_and_cortisone_in_human_urine_comparison_of_mass_spectrometry_and_fluorescence_detection"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="8" data-entity-id="77654112" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/77654112/Trends_in_Analysis_of_Cortisol_and_Its_Derivatives">Trends in Analysis of Cortisol and Its Derivatives</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="1072444" href="https://okcu.academia.edu/AliBoolani">Ali Boolani</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Advances in experimental medicine and biology, 2019</p><p class="ds-related-work--abstract ds2-5-body-sm">Determination of concentration of cortisol in various biological fluids can provide extensive information about a person&#39;s health. Historically, cortisol and its derivatives were (and still are) determined using immunoaffinity-based methods such as colorimetric ELISA assay, chemiluminescent immunoassay, fluorescence assays, radioimmunoassay, electrochemiluminescence immunoassay, immunochromatographic test, or sensors and immunosensors. Recently, mass spectrometry (MS)-based methods started to be used in determination of cortisol and its derivatives. These MS methods are net superior to immunoaffinity-based assays, but are not easily applicable and are also time-consuming and price prohibitive. Furthermore the standard MS instruments used are triple quadrupole instruments. Here we review the literature on the MS and non-MS based methods for determination of cortisol and its derivatives and also explore the use of a less used quadrupole-time of flight instrument in determination o...</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Trends in Analysis of Cortisol and Its Derivatives","attachmentId":84965869,"attachmentType":"pdf","work_url":"https://www.academia.edu/77654112/Trends_in_Analysis_of_Cortisol_and_Its_Derivatives","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/77654112/Trends_in_Analysis_of_Cortisol_and_Its_Derivatives"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div><div class="ds-related-work--container js-wsj-grid-card" data-collection-position="9" data-entity-id="18442404" data-sort-order="default"><a class="ds-related-work--title js-wsj-grid-card-title ds2-5-body-md ds2-5-body-link" href="https://www.academia.edu/18442404/Cortisol_and_cortisone_analysis_in_serum_and_plasma_by_atmospheric_pressure_photoionization_tandem_mass_spectrometry">Cortisol and cortisone analysis in serum and plasma by atmospheric pressure photoionization tandem mass spectrometry</a><div class="ds-related-work--metadata"><a class="js-wsj-grid-card-author ds2-5-body-sm ds2-5-body-link" data-author-id="38450035" href="https://independent.academia.edu/MarkKushnir">Mark Kushnir</a></div><p class="ds-related-work--metadata ds2-5-body-xs">Clinical Biochemistry, 2004</p><div class="ds-related-work--ctas"><button class="ds2-5-text-link ds2-5-text-link--inline js-swp-download-button" data-signup-modal="{"location":"wsj-grid-card-download-pdf-modal","work_title":"Cortisol and cortisone analysis in serum and plasma by atmospheric pressure photoionization tandem mass spectrometry","attachmentId":40065897,"attachmentType":"pdf","work_url":"https://www.academia.edu/18442404/Cortisol_and_cortisone_analysis_in_serum_and_plasma_by_atmospheric_pressure_photoionization_tandem_mass_spectrometry","alternativeTracking":true}"><span class="material-symbols-outlined" style="font-size: 18px" translate="no">download</span><span class="ds2-5-text-link__content">Download free PDF</span></button><a class="ds2-5-text-link ds2-5-text-link--inline js-wsj-grid-card-view-pdf" href="https://www.academia.edu/18442404/Cortisol_and_cortisone_analysis_in_serum_and_plasma_by_atmospheric_pressure_photoionization_tandem_mass_spectrometry"><span class="ds2-5-text-link__content">View PDF</span><span class="material-symbols-outlined" style="font-size: 18px" translate="no">chevron_right</span></a></div></div></div></div><div class="ds-sticky-ctas--wrapper js-loswp-sticky-ctas hidden"><div class="ds-sticky-ctas--grid-container"><div class="ds-sticky-ctas--container"><button class="ds2-5-button js-swp-download-button" data-signup-modal="{"location":"continue-reading-button--sticky-ctas","attachmentId":46169359,"attachmentType":"pdf","workUrl":null}">See full PDF</button><button class="ds2-5-button ds2-5-button--secondary js-swp-download-button" data-signup-modal="{"location":"download-pdf-button--sticky-ctas","attachmentId":46169359,"attachmentType":"pdf","workUrl":null}"><span class="material-symbols-outlined" style="font-size: 20px" translate="no">download</span>Download PDF</button></div></div></div><div class="ds-below-fold--grid-container"><div class="ds-work--container js-loswp-embedded-document"><div class="attachment_preview" data-attachment="Attachment_46169359" style="display: none"><div class="js-scribd-document-container"><div class="scribd--document-loading js-scribd-document-loader" style="display: block;"><img alt="Loading..." src="//a.academia-assets.com/images/loaders/paper-load.gif" /><p>Loading Preview</p></div></div><div style="text-align: center;"><div class="scribd--no-preview-alert js-preview-unavailable"><p>Sorry, preview is currently unavailable.
