Introduction: Booking Blood Tests Online in St Helens 2025
In 2025, scheduling a blood test online in St Helens is the norm—not a convenience. As NHS Trusts and community services transition to appointment-only systems, we help numerous residents book their tests efficiently. In this detailed guide, we explain step-by-step how to reserve a blood test slot online, which clinics you can choose, what to prepare, and how to handle special scenarios. By following this process, you avoid long waits, confusion, or being turned away.
Why You Must Book: Walk‑Ins Are No Longer Accepted

Beginning 29 November 2021, all phlebotomy clinics in St Helens transitioned to an appointment-only system. According to St Helens Cares, walk-ins are no longer accepted at the hospital or community clinics.
Health officials confirmed that both St Helens and Whiston hospitals, along with community clinics, now require an appointment for blood tests. This change aims to reduce crowding, streamline workflow, and allow patients to select convenient times. Ignoring this requirement could lead to being turned away.
Getting the Required Blood Test Requisition
Before you can book anything, you must obtain a blood test form (also called a “referral” or “request form”) from your GP, hospital consultant, or health clinic. This document:
- Specifies which tests are required
- Contains patient identifiers and lab codes
- It is mandatory to be present at your appointment
Without a valid form, you may be refused service. Make sure the form is correctly completed and legible.
Online Booking Portal: How to Access & Navigate

Once your requisition is ready:
- Go to St Helens Cares / SimplyBook portal (for adult phlebotomy appointments). Input necessary information (patient name, date of birth, requisition code)
- Choose “Book a blood test/phlebotomy appointment”
- Select a clinic and time slot from the available options
- Confirm your appointment
If you prefer, you can also call 0808 196 4500 (weekdays 12 PM–3 PM) to book by phone.
Be aware: phone booking is limited to certain hours, while the online portal stays open 24/7.
Choosing Clinic Location & Time Slot
When selecting your clinic and time:
- Opt for sites near you—hospital outpatient labs, community centers, or phlebotomy clinics
- Check morning slots—many fasting tests are scheduled early
- Some clinics operate restricted hours (e.g., Millennium Centre 7 AM–9 AM for UTC/urgent tests)
- Ensure the chosen clinic accepts your particular requisition (some clinics serve specific GP areas or test types)
St Helens & Knowsley Phlebotomy Sites
Phlebotomy (blood test) services are conducted in multiple locations across St Helens & Knowsley. Important ones include:
- St Helens Hospital, Marshall Cross Road
- Whiston Hospital, Warrington Road
- Millennium Centre, St Helens town centre (Urgent Treatment Centre)
- Newton Community Hospital
- Lowe House Resource Centre
- Garswood Resource Centre
Each site runs pre-booked appointments only.
Note: Millennium Centre’s UTC clinic no longer accepts walk-ins and uses an appointment system between 7 AM and 9 AM.
Required Documents & Preparations
To avoid issues, bring the following:
- Your blood test form/requisition
- A valid photo ID (if requested)
- NHS number (optional but helpful)
If your test requires fasting, follow instructions—often no food or drink (except water) 8–12 hours before the draw. Otherwise, a regular diet is usually acceptable.
Also, ensure you’re hydrated (drinking water) the day before, which helps ease venipuncture.
On the Day: What to Do at Your Appointment
At the appointment:
- Arrive early (5–10 minutes ahead)
- Register at reception, show form and ID
- The phlebotomist draws your blood—usually a quick process
- You may rest briefly following the draw
- Ask any questions about post-test care or potential side effects
Clinics often schedule patients to minimize waiting time.
If you feel faint, inform staff—they can take precautions.
What Happens After the Test: Results & Follow‑Up

Once your sample is processed:
- Results are sent to your referring clinician or GP
- Simple tests might return the same day; more complex panels may take several days
- If results show urgent or abnormal findings, your doctor will contact you directly
- For routine results, check through your GP or patient portal
Exceptional Cases: Children & Home Visits
- For under‑16 patients, bookings must be made via phone, not online.
- / Domiciliary sampling is available for housebound patients by request through community phlebotomy services.
Ensure your requisition form indicates these special requirements when you request the booking.
Common Pitfalls & How to Avoid Them
- No available slots — try alternate clinics or early morning times
- Incorrect or missing requisition form — double-check before booking
- Arriving at the wrong clinic — confirm the address and location ahead of time
- Failing to follow fasting instructions — treat fasting tests seriously
- Missing appointment — always cancel or reschedule in advance
Planning and checking details can prevent most issues.
Tips for Smooth Booking & Attendance
- Book as early as possible—slots often fill quickly
- Use clinics with early morning hours for fasting tests
- Keep your blood form and ID accessible
- Allow time for parking and travel
- If you can’t make it, cancel early to free the slot
