O dan y rheolau presennol, mae preswylwyr Cymru wedi gorfod prynu prawf y Gwasanaeth Iechyd Gwladol (GIG). Mae’r rheolau hyn yn wahanol i’r rheini ar gyfer pobl sy’n byw mewn rhannau eraill o’r DU – gall y bobl hynny brynu profion oddi wrth ddarparwyr preifat.
Under our current rules, Welsh residents have had to purchase an NHS test. This is different from the rules for people living in other parts of the UK – they are able to buy tests from other private providers.
