The routine blood test GPs use looks at many parts of your blood, including a type of cell called platelets.
Platelets can vary depending on your age and sex.
High platelet levels can happen for a variety of reasons, such as common infections and inflammation, or something more serious.
Most people with a high platelet count do not have cancer, but it’s one of several things a GP might consider when deciding what to do next.
It’s part of a new approach that helps GPs identify and decide if a routine blood test result may need further consideration.
