Diagnostic Sample Integrity

Meaning

Diagnostic sample integrity refers to the condition of a biological specimen—such as blood, saliva, or urine—remaining unaltered and representative of the patient’s physiological state from the moment of collection through to the point of laboratory analysis. Maintaining integrity is paramount in hormonal health diagnostics, as compromised samples, due to improper collection, storage, or transport, can lead to pre-analytical errors and clinically misleading results. Clinicians rely on high sample integrity to ensure the accuracy of hormone levels and biomarkers, which is foundational for precise therapeutic intervention and monitoring.
