Sample Matrix

HHEAR provides laboratory analyses of wide variety of sample matrices. The type of biospecimen or environmental sample, the volume available, and how the samples were collected and stored will affect the feasibility of requested analyses. The sample matrixes most commonly analyzed by HHEAR are urine, plasma, serum, whole blood, house dust and silicone wristbands. For other matrices (particularly those noted with *), consultation with a HHEAR Lab Hub is important to determine appropriateness in your proposed HHEAR project.
