Pathology services at the London Clinic

We are committed to consistently delivering the highest standards of clinical excellence for which The London Clinic is renowned. Our laboratories are medically-led by experienced Consultants and staffed by qualified biomedical scientists.

We offer a full walk-in service and appointments are only necessary if the patient needs a specialised test e.g. glucose tolerance test. All samples are taken by qualified staff.

Fees for pathology

Fees can be paid directly by patients, the practice/clinic or by the requesting organisation. Please note that we require a complete permanent UK address for accounts to be settled by the patient. The London Clinic does not send accounts overseas.

We accept all major credit cards. If an outpatient has private medical insurance with a major UK insurer, the patient will need to present their policy number and authorisation code when they register at the outpatient department.

Domiciliary services

These can be organised by prior arrangement during normal working hours. Please contact the department directly on 020 7034 6320.

Patients must be referred by their GP or a consultant and should bring their request form or referral letter with them.

Request forms can also be faxed or emailed by the referring doctor before the patient arrives at the Clinic.

Policy on patient request form and specimen ID

In order for The London Clinic to provide you with the highest quality service, it is important that you provide us with a completed request form to include:

  • Patient’s full name – first name and surname
  • Date of birth
  • Hospital MPI number (if known)
  • Sample collection time and date
  • Type of sample and, if appropriate, anatomical site
  • Relevant clinical information

It is mandatory for blood grouping and cross-match samples and request forms to have a four point patient ID:

  • Patient’s full name – first name and surname
  • Date of birth
  • Hospital MPI number or full home address

Self-adhesive address labels will be accepted on request forms. However, we discourage their use on specimen bottles and containers and we cannot accept samples for blood transfusion unless the information has been hand-written. 

Where multi-part request forms are used, please ensure that a label is affixed to each copy of the form and that ball-point pen is used to complete the form.

If additional tests are required for a sample that we have already received, please contact the laboratory immediately with your request as samples are not kept indefinitely.

It is important that your request forms contain full clinical details. This important information enables us to interpret the significance of results and ensure that we provide you with the appropriate interpretive comments and age/sex related reference ranges.

Specimens may not be suitable for testing if they are inadequately labelled or if they have leaked or been contaminated. In these circumstances every effort will be made to inform the requesting clinician before discarding the specimen. In the case of a ‘precious’ sample which has been incompletely labelled, analysis will be carried out at the discretion of the laboratory manager.

Supplies and postal packs

Request forms, specimen bottles (vacutainers), urine containers, swabs and cervical cytology kits are all available free of charge to clients using the services of The London Clinic.

You can order secure, UK postal compliant, hard pack specimen postal kits for your patients’ convenience.

To request postal supplies, please contact Angela Leong on 020 7034 6320. Clinical departments within The London Clinic may obtain their supplies directly from our stores department.

Specimen transport and collection service

We require each specimen to be sealed in a separate specimen bag with the accompanying request form in the external pocket. The specimen form should not be placed in the same pocket as the specimen. ‘High Risk’ samples must be appropriately labelled. CSF specimens for xanthochromia should be protected from light whilst in transit.

The Pathology department employs porters who collect samples within The London Clinic and from consulting rooms within the Harley Street/Wimpole Street area between the hours of 9am to 6pm Monday to Friday.

To request a pathology pick-up please call T: 020 7616 7755.

Our client services team can arrange couriers if collection is outside our local area. We will accept delivery of specimens to the sample reception area located at 116 Harley Street from 8am to 7pm, Monday to Friday and from 9am to 1pm on Saturday. We will accept delivery outside these hours by prior arrangement.

24 hour urine collections procedures

For 24 hour urine collections, patients should follow these instructions:

  • Discard the first morning sample passed and note the time of passing
  • Collect all urine passed during the next 24 hours (up to and including the next early morning collection)
  • Keep bottle in a cool place and send to laboratory as soon as possible.

Some investigations require a preservative (usually 1.0M hydrochloric acid) to be added to the specimen bottle. All bottles containing a preservative are clearly labelled.

If you request creatinine clearance, please note that a blood sample should be collected not more than 48 hours before or after the 24 hour urine collection period.

Results services

For professionals

Clinicians can access patient results directly from our pathology database via a secure internet link.

We deliver reports by courier in the Harley Street/Wimpole Street area or post them first class. In addition, if required, we can deliver reports by fax or secure email.

If you wish to use the auto-faxing service, you are responsible for ensuring that faxed reports are received in a secure area and read only by authorised persons.

All reports include a reference or therapeutic range and interpretative comment(s) where appropriate.

If there are any unexpected abnormal and/or critical results, we will notify the requesting clinician by telephone immediately.

Turnaround times for routine requests are listed on our A-Z test listing. Please note that where a test turnaround time is quoted in days this refers to working days and not calendar days.

For patients and third parties

We only disclose details of test results to patients or third parties if we have received prior, written authorisation from the requesting clinician. In the absence of satisfactory authorisation, we will ask the patient to contact the requesting clinician directly for their results.

We will send copies of results to bona fide third party clinicians on request. To do this, we require a full address including postcode. If we are unfamiliar with the clinician, we will verify them prior to dispatching reports.

We reserve the right to retain results if we are unable to establish the credentials of a clinician.


The pathology department welcomes constructive feedback from its users on the services provided. This is important and assists us in improving the service that we deliver.

Should our service delivery not meet with your expectations, in the first instance please contact the laboratory general office on 020 7616 7755. If we are unable to resolve your problem at this point we will take your contact details and escalate the issue to the most appropriate person in the department who will call you back within a mutually agreed timescale. Please contact us as soon as possible as in many cases we will be able to resolve the problem without delay to your patient’s treatment.

If you would prefer to write to us, please address your letter to Beverley Barker, Pathology Quality Manager. All written communications will be acknowledged within two working days of receipt in the department.

If you remain dissatisfied with the response from the department please contact the Head of Laboratory and Cardiology Services.

In the event you do wish to make a formal complaint to The London Clinic, we have a thorough process which is detailed in the booklet "Your opinion matters to us" which is displayed in all patient areas in The Clinic.  All comments and complaints are investigated thoroughly and in a confidential manner; we endeavour to resolve all problems as quickly as possible.

The London Clinic complaints process follows the code of practice agreed with the Independent Healthcare Advisory Services (IHAS), which is the representative body for Independent Hospitals.  The Clinic is also a member of the Independent Sector Complaints Adjudication Service (ISCAS).
