Sport Ireland collected 2,029 samples (urine, blood serum, blood ABP, and DBS) in 2024, across 35 different sports. Out-of-competition samples accounted for 78% of samples collected.

Sport Ireland determines the most appropriate analyses for each urine, blood, serum, or DBS sample through combined science and testing expertise. All samples are tested for a standard list of substances based on whether they are collected in-competition or out-of-competition. Additionally, special analysis can be conducted beyond the basic screen to detect specific substances, such as erythropoietin (EPO) and growth hormone (GH), depending on the results of the basic screen and/or the evaluation of other data.

Sport Ireland also conducts testing under the User Pays Programme, where other sports organisations – NGBs or IFs – pay for the sample collection procedure of testing to be carried out on their behalf. In 2024, 241 samples were collected under this programme – 203 urine samples, 26 blood samples, 3 blood ABP samples and 9 DBS samples.
