Abstract

Biological specimen collection is an integral part of many longitudinal epidemiological studies. It is important to achieve high participant satisfaction for continuing involvement, and high sample quality for accurate biomarker measurement. We conducted a study to evaluate these issues on the sample collection proposed for the Canadian Longitudinal Study on Aging (CLSA). There were 85 participants recruited, and 65 attended either a hospital laboratory or private laboratory. Approximately 100 mL of blood and a random urine specimen were collected from each participant for a total of 2,108 sample aliquots. Quality standards were met for more than 90 per cent of samples and were similar for samples collected in both laboratories. More than 90 per cent of participants rated satisfaction with the collection as being good or excellent, and 84 per cent would be willing to repeat the collection in one to three years.

Résumé

La collecte de spécimens biologiques est une partie intégrale de beaucoup d’études épidémiologiques longitudinales. Il est important d’obtenir un haut taux de satisfaction de la part des participants pour que leur participation soit continue et pour assurer une qualité élevée des échantillons pour avoir des mesures précises pour les biomarqueurs. Nous avons réalisé une étude pour évaluer ces questions sur la collecte d’échantillons proposée pour l’Étude longitudinale canadienne sur le vieillissement (ÉLCV). Parmi les 85 participants recrutés, 65 ont été dirigés vers un laboratoire d’hôpital ou un laboratoire privé. Environ 100 mL de sang et un prélèvement aléatoire d’urine ont été collectés pour chaque participant, pour un total de 2 108 aliquots d’échantillon. Les niveaux de qualité ont été atteints pour plus de 90 % des échantillons et étaient semblables pour les échantillons collectés dans les deux laboratoires. Plus de 90 % des participants ont exprimé que leur satisfaction par rapport à la collecte était bonne ou excellente, et 84 % serait prêts à répéter la collecte dans un à trois ans.
