Private vs NHS: What’s the Difference?

Both options are beneficial. Private testing emphasizes speed, convenience, and a wide range of choices:

  • Quick Access: same-day appointments; many results available within 24 hours.
  • Selection of Tests: choose the specific tests you need, or let us recommend them.
  • Consultation with a Clinician: include a results review for personalized guidance.

NHS services are crucial for long-term care and treatment plans. Opt for private testing if you require quick results, specific test panels, or easy access in central London.

On the day: check in, meet with a phlebotomist, and the appointment usually takes only a few minutes.
