description | Polyunsaturated fatty acids such as DHA have known anti-inflammatory properties. The therapeutic implication highlights the importance of accurate serum measurements. Sample preservation is challenging when performed parallel to the clinical obligations. Impact of time between sample collection and processing regarding concentration alterations of fatty acids in human blood remains to be elucidated. Therefore, more information is required with respect to the stability and storage options in the context of potential degradation and concentration changes. This study investigates the stability of DHA in serum samples over time, given the challenges of timely sample analysis in clinical settings. Blood samples from three patients were collected and stored at +4 °C. Concentrations were analysed between 6 h and 7 days post-collection. Our data indicate that DHA concentrations remained unchanged during the observational period. Our results suggest that storage duration up to 7 days before sample processing does not affect accuracy of the results. DHA measurements is crucial for ongoing and future research in cardiovascular and inflammatory diseases. Our results reveal that DHA stability remains consistent over one week. This information is important for further clinical studies investigating PUFA concentrations, providing researches the option to postpone processing of samples if required along the clinical obligations. |
