Ceir rhestr o ddarparwyr profion preifat ar wefan Llywodraeth y DU, sy’n cynnig profion PCR, weithiau am brisiau rhatach.  Nid yw Llywodraeth y DU yn cymeradwyo nac argymell dim un o’r darparwyr hyn.  Mae gan Lywodraeth Cymru bryderon am y gwasanaeth a ddarperir gan rai o’r darparwyr preifat hyn dros amryw o faterion, gan gynnwys methu â chyflenwi profion a archebwyd a methu â rhoi’r canlyniadau i bobl.  Rydym yn benderfynol o amddiffyn cyhoedd Cymru rhag cwmnïau nad ydynt yn bodloni’r safonau sy’n ofynnol gennym.
There is a list of private test providers on the UK Government’s website who offer PCR testing, sometimes at cheaper prices. The UK Government does not endorse or recommend any of these providers. The Welsh Government is concerned about the level of service provided by some of these private providers across a range of issues, including booked tests not being delivered and people not being notified of results. We are determined to protect the Welsh public from companies who do not meet the standards we require.
