Clinical scientist

Clinical scientists research and develop techniques and equipment to help prevent, diagnose and treat illness.


What you'll do

Day-to-day tasks

There are 4 main areas of clinical science. Depending on your area you could:

  • analyse data from genetic material to trace how diseases develop
  • research and test methods to improve diagnoses and treatments
  • assess abnormalities in different parts of the body
  • study cells or diagnose and analyse blood disorders
  • investigate the causes of illness or death
  • instruct medical staff on how to use instruments and equipment

Working environment

You could work in an NHS or private hospital, in a laboratory or at a university.

You may need to wear protective clothing.

What it takes

Skills and knowledge

You'll need:

  • knowledge of biology
  • thinking and reasoning skills
  • excellent verbal communication skills
  • the ability to use your initiative
  • science skills
  • to be thorough and pay attention to detail
  • complex problem-solving skills
  • maths knowledge
  • to be able to use a computer and the main software packages confidently

Most relevant

  • Biology - Clinical scientists work extensively with biological systems – analysing genetic material, studying cells, diagnosing blood disorders, and investigating the causes of illness. A strong understanding of human biology, genetics, and how diseases develop is fundamental to almost every area of this career.
  • Chemistry - Clinical scientists use biochemical techniques to analyse blood samples, identify abnormalities, and test new diagnostic methods. Understanding chemical reactions, molecular structures, and laboratory techniques like spectroscopy is essential for the analytical work they carry out daily.
  • Physics - Clinical scientists working in areas like medical physics use imaging technologies such as MRI, ultrasound, and CT scanners, all of which rely on physics principles. Understanding radiation, waves, and how energy interacts with the body is crucial for developing and improving diagnostic equipment.
  • Mathematics - Clinical scientists analyse complex datasets, use statistics to interpret research findings, and apply mathematical models to understand how diseases progress. Accurate calculations are also essential when calibrating equipment and assessing diagnostic test results.

Also relevant

  • Computer Science - Clinical scientists increasingly work with large datasets from genetic sequencing and diagnostic imaging that require computational analysis. Some specialisms involve developing algorithms or using bioinformatics tools to identify patterns in biological data.
  • Psychology - Clinical scientists sometimes work in neurophysiology or other areas where understanding brain function and human behaviour is important. They may also need to communicate sensitive diagnostic findings to patients and medical teams in a clear and empathetic way.
  • English Language - Clinical scientists write detailed research reports, present findings to medical teams, and contribute to scientific publications. Being able to explain complex scientific information clearly – whether in writing or verbally – is important for ensuring their work is understood and applied correctly.
  • Engineering - Clinical scientists who specialise in clinical engineering develop, maintain, and improve medical equipment used in hospitals. Understanding engineering principles helps them design better diagnostic tools and ensure that complex instruments work safely and accurately.

How to become

You can get into this job through:

  • a university course
  • an apprenticeship
  • an NHS training programme for non-graduates

You can do a degree to start your training as a clinical scientist.

Subjects include:

  • life sciences
  • biology or biochemistry
  • genetics
  • biomedical science
  • medical physics

After completing your degree, you can apply for the NHS Scientific Training Programme (STP). During the 3-year programme, you'll combine employment in the NHS with study for a postgraduate master's degree.

Entry requirements

You'll usually need:

  • 2 or 3 A levels, or equivalent, including a science, for a degree
  • a degree in a relevant subject for postgraduate study

More Information

You could apply for a place on a higher or degree apprenticeship, such as:

  • Healthcare Science Associate Level 4 Higher Apprenticeship
  • Healthcare Practitioner Level 6 Degree Apprenticeship
  • Clinical Science Level 7 Postgraduate Apprenticeship

When you finish your apprenticeship, you can apply to join one of the NHS training programmes and continue your training to become a clinical scientist.

Entry requirements

You'll usually need:

  • 4 or 5 GCSEs at grades 9 to 4 (A* to C) and A levels, or equivalent, for a higher or degree apprenticeship

More Information

If you do not have a degree, you could apply to join the NHS Practitioner Training Programme (PTP).

During the 3-year programme, you'll be employed in the NHS and study for an accredited university degree in healthcare science.

If you work as a healthcare science associate in the NHS, you may be able to apply for a place on the PTP.

Registration

Career tips

When looking to join an NHS training programme or an apprenticeship, you'll be expected to have an understanding of how NHS values apply in your work.
