Study type

Development and validation of an analytical workflow for detecting doping agents
“In the present study, we report a fast, streamlined, and harmonized analytical workflow to detect 54 prohibited peptidic and non-peptidic compounds in dried blood spots, serum, and plasma.”

Subjects

Dried blood spots, serum, and plasma matrices containing 54 prohibited peptidic and non-peptidic compounds
“In the present study, we report a fast, streamlined, and harmonized analytical workflow to detect 54 prohibited peptidic and non-peptidic compounds in dried blood spots, serum, and plasma.”

Duration

Stability studies conducted for at least two months at -20 °C and one week at 4 and 22 °C
“Stability studies showed that all compounds were stable (variation lower than 15%) for at least two months at -20 °C in all the blood matrices considered.”

Reported findings

The method demonstrated satisfactory performance with detection limits between 0.05 and 1.25 ng mL-1
“The validation results showed satisfactory performance with respect to selectivity (no interferences were detected at the retention times of the analytes), detection limits (0.05-1.25 ng mL-1), carry-over (no signals in the negative sample injected after the positive sample), matrix effect (5-33%), extraction yield (15-80%), and extract stability (the target analytes were stable for at least 72 h in the autosampler at 10 °C).”
All compounds remained detectable in dried matrices throughout the study duration, unlike in liquid matrices where some degraded
“In contrast, in dried matrices all compounds remained detectable throughout the entire duration of the study, indicating that samples can be transported and stored under non-refrigerated conditions, thereby reducing costs.”
Specific compounds showed extensive degradation in serum and plasma after one week at 4 and 22 °C
“At 4 and 22 °C, alexamorelin, AOD9604, buserelin, hGH 176-191, kisspeptin-10 and LHRH were extensively degraded after one week in serum and plasma, whereas BPC-157, TB500, vasopressin, lypressin, and terlipressin showed complete degradation only in serum.”
