There is no statutory definition of fair dealing and, in a court of law, use would be judged on a case-by-case basis.

‘Fair dealing’ includes the use of works for illustration for instruction and quotation. Works made available to the public can be used for criticism and review.

In essence, ‘fair dealing’ means use is limited to only the minimum necessary amount of content for its purpose (reasonable and appropriate to the context) and use does not negatively impact on the market for the original works. Copying should not harm the copyright holder, financially or otherwise.

The Full Blood Count (FBC, also termed Complete Blood Count, CBC) provides information on the cellular contents of the blood: red blood cells, white blood cells (e.g. WBC) and platelets.

Fresh frozen plasma (FFP) is made from the liquid portion of whole blood. 

FFP is used to replace low blood clotting factors or low levels of other blood proteins, and can be used to treat TTP.

The Faecal Immunochemical Test (FIT), also termed Quantitative Faecal Immunochemical Test (qFIT), is used in bowel cancer screening.

qFIT uses antibodies that specifically recognise human haemoglobin and is therefore more sensitive and specific than the older guaiac-based FOB test.
