MRCP and PLAB are two professional examinations that must be taken before a non-European doctor can be allowed to practice in the United Kingdom. While both exams need to be done, there are some differences between the two. PLAB is the short form of the Professional and Linguistic Assessment Board. It is an examination that is aimed at assessing non-European doctors to know whether they are fit to work in the United Kingdom. This examination is in two different stages.
The first one can be done anywhere in the world, while the second one is usually conducted in London at the General Medical Council building. If you are able to pass this examination, it means you are qualified, but that alone doesn't guarantee any job. MRCP is the short form of Member of the Royal College of Physicians. This is an examination that will earn you any level of medical training in the UK if you are a non-European doctor.
