Ar hyn o bryd, mae dwy ffordd wahanol o brofi yng Nghymru; prawf i ganfod a oes gan rywun y feirws ar y pryd, a'r prawf gwrthgyrff a ddefnyddir yn bennaf i ddarganfod a yw person wedi'i heintio yn flaenorol.  Mae’r strategaeth yn ein hatgoffa nad yw profi yn rhywbeth sy’n cael ei wneud er mwyn gwneud hynny, ond y dylai fod diben clir i’r profi yn seiliedig ar dystiolaeth. Mae’r Strategaeth hefyd yn amlinellu:rôl barhaus profi asymptomatig a sut y gellir ei ddefnyddio lle ceir achosion o’r feirws ac i brofi grwpiau sy’n wynebu risg uwch o gael eu heintio gan COVID-19, megis pobl hŷn a gweithwyr gofal ac iechyd;diben profion gwrthgyrff wrth ddeall serogyffredinolrwydd. Hyd yn hyn mae dros 32,000 o brofion wedi cael eu cynnal ymhlith gweithwyr gofal iechyd mewn lleoliadau gofal eilaidd, cynradd a chymunedol, yn ogystal a staff dysgu. Mae gweithwyr gofal cymdeithasol a phreswylwyr yn flaenoriaeth, ac mae rhaglen beilot yn cael ei datblygu i gynnal profion gwrthgyrff sy’n defnyddio ffordd newydd o brofi sy’n llai mewnwthiol.
There are currently two different forms of testing in Wales: virus detection, which shows if someone currently has Covid-19; and antibody testing, which is used to determine whether a person has been infected previously.  The strategy reminds us that testing is not something that is just done and counted but that testing should have a clear purpose underpinned by evidence.  The Strategy also sets out:the continued role of asymptomatic testing and how it can be used in outbreaks and to test groups facing the greatest risks of contracting and being infected by Covid-19, such as older people and health and care workers; andthe purpose of antibody testing in understanding seroprevalence. To date over 32,000 tests have taken place amongst healthcare workers in secondary, primary and community care settings and of teaching staff.  Social care workers and residents are a priority and a pilot is being developed to undertake antibody testing using a new and less invasive form the test.
