FINA have provided an update on their programme from the first quarter of the year, between January and March.

It comes with less than 100 days to go before the start of the World Aquatics Championships, which will take place in Hungary's capital Budapest.

According to FINA, more than 600 procedures were carried out during the three month period, with 376 athletes providing samples.

This selection came from 38 countries, with the out-of-competition work consisting of a variety of tests and analysis. 

FINA said this included urine samples, blood samples for the athlete passport or blood samples for the detection of prohibited substances and methods.

Prior to the World Championships in July, the governing body have indicated that around 2,000 out-of-competition procedures will be carried out.

It is claimed this will represent an investment of near $2 million (£1.6 million/€1.9 million) by FINA.

The World Championships will be held between July 14 and 30, with the eyes of the world set to be on Budapest after their bid for the 2024 Olympics and Paralympics was withdrawn amid referendum fears.

The Danube Aquatics Arena will stage the swimming, diving and synchronised swimming, with the recently inaugurated venue receiving praise from FINA officials last month.

The Alfréd Hajós National Swimming Stadium will stage the water polo competitions, while high diving, recently introduced to the World Championships programme, will be hosted at the Batthyányi Square embankment, facing the city's Parliament buildings.

Budapest stepped in to stage the event after original hosts, Mexican city Guadalajara, pulled out due to fears over falling oil prices in 2015.

The city was initially due to stage the 2021 edition, which has since been awarded to Fukuoka in Japan.
