This document describes the services provided by TGLclinical to internal and external users.
The laboratory is situated in the Brookes Lawley Building, on the Sutton campus of the
Institute of Cancer Research (ICR).
TGLclinical provide a molecular diagnostic service for germline mutation analysis of genes
that confer a predisposition to cancer. Uniquely TGLclinical provides an integrated laboratory
and clinical interpretation service utilising expertise based at ICR and RMH to test for and
interpret germline variation in cancer predisposition genes to aid and inform clinical
management decisions.

Hours of service:
9.00am to 5.00pm, Monday to Friday (excluding bank holidays).
Out of hours service:
No out of hours service is provided. Samples received after 5.00pm will be processed the
following working day.
Instructions for completion of the request form:
Please fill ALL the fields provided with the relevant demographic/clinical information. For
patient details, stickers with the patient’s information can be used. Similarly, stickers can be
used for the Consultant and referring hospital information.
If some information is unknown or not applicable please fill the field in with “UNKNOWN”
and “N/A”, respectively, rather that leaving it blank. Samples with attached request forms
that do not contain all the relevant information can be rejected by the lab or put “on hold”
until a new and completely filled request form has been received.
Clinical details, required investigations and family history should be filled in where possible. If
in doubt please contact us on the laboratory email or numbers given above.
Consent:
Upon receipt of samples, the laboratory assumes that appropriate consent has been
obtained by the referring clinician.

Cancer predisposition gene tests not performed by TGLclinical:
When requests are received for cancer predisposition gene tests not offered by TGLclinical
we will arrange testing by external providers. These providers will have Clinical Pathology
Accreditation (CPA), and may also have accreditation to the internationally recognised
standard ISO15189:2012. When the results are received by TGLclinical, they are forwarded to
the referring clinician with a clear indication as to the accreditation status of the external
laboratory. Reporting times and accreditation status of the external labs are monitored by
TGLclinical.
DNA storage:
We can store DNA from individuals for which no test is currently indicated, but for which it is
considered possible that testing may be appropriate in the future. We do not store blood
samples and thus if blood samples are received for storage the DNA is extracted and stored.

95% within 42 calendar days
(TGLclinical target turnaround time)
Specific Mutation Testing
90% urgent tests within 14 calendar days
(UK National target turnaround time)
90% non-urgent tests within 28 calendar

Reporting of service and standards
Where TGLclinical undertakes more than 10 tests per month for any individual institution a
monthly report will be provided within the first seven working days of the following month,
which will include the following information:
Number of tests
Test type
Referring department and/or clinician
Average turnaround times per test type
Specimens required:
Please send 2 x 9mls of blood in PLASTIC EDTA tubes. Smaller volumes, for example from
children, can be extracted if necessary, but we require a minimum of 2mls. Samples should be
sent on the day of collection and at ambient temperature.
DNA samples can also be received.
We strongly prefer to receive blood samples but if this is not possible, please contact the lab to
discuss sending a saliva sample.
Unsuitable samples:

Clotted samples are occasionally unsuitable for molecular analysis, where possible
the referring clinician will be informed and a new sample requested.
 Samples should be labelled with the patient first name and surname, D.O.B., hospital
number and the date and time the sample was taken. The details on the sample tube
must correspond to those on the request form. At least two unique identifiers are
required.
Unidentifiable/Unlabelled samples will NOT be accepted. Where possible the referring
clinician will be informed and a new sample requested.
Please note that all DNA samples are stored indefinitely unless otherwise requested.

Transportation of samples:
Internal samples will be sent together with the request form from the phlebotomy unit to
the Royal Marsden Hospital Central Pathology Department at the Sutton site, or can be
delivered to TGLclinical pigeon hole at BLB reception. Samples should be dispatched as soon
as possible after taking the sample. In the case of samples sent from the Chelsea site, they
will be transported in the pathology containers on the RMH inter-site coach, to be delivered
to the RMH Central Pathology. Samples will be then collected from the RMH Central
Pathology and the BLB pigeon hole by laboratory staff. See HSE guidance on
http://www.hse.gov.uk/biosafety/biologagents.pdf
Blood and DNA samples from external users should be sent by first class mail, please address
specimens to the TGLclinical postal address given above. Any diagnostic sample sent to the
laboratory should be sent in accordance with the UN3373 regulations and the P650
Packaging instruction (http://www.un3373.com/info/regulations).
