Wellness that works around your day
Health should be easy to keep up with. That’s why we’ve designed our call-out service to fit around your schedule, not the other way round.
Instead of travelling to a clinic, you can book your treatment at home or at work and receive the same professional care in a setting that suits you best.
What we offer as call-outs
Same-day blood test results through our exclusive laboratory partner.
Access to DefinitIV 360°, our personalised wellness service built around your blood.
On-demand blood tests with home visit availability.
IV therapy delivered to your home or office.

We confirm the details
Our team will call you to confirm your appointment, answer any questions, and make sure everything is in place before your visit.
We come to you
A qualified nurse arrives with all required equipment and carries out your appointment safely and professionally at your home or office.
Get your results or begin treatment
If you’ve booked a blood test, your results are returned within 24 hours through our exclusive laboratory partner. If you’ve booked IV therapy, your treatment is administered during the appointment.
Professional treatment, wherever you are
Every call-out is carried out by a qualified nurse using sterile, pharmaceutical-grade ingredients and strict clinical protocols.
Whether you’re booking a rapid IV treatment or an advanced blood panel, you receive the same high standard of care you would expect in clinic, with the added convenience of staying exactly where you are.
