Blood Sciences Department Pathology Building Level E Queen Alexandra Hospital Cosham PO6 3LY 023 9228 6271 Patient instructions: Collecting Faecal Occult Blood Samples - Version: 1.0. Index: LI-BSL-BS-FOBInstructions. Printed: 13-Mar-2013 15:13 Patient information sheet: Collection of a Faecal Occult Blood Specimen Introduction Your doctor has asked that you collect a series of stool samples for testing in the laboratory to check for the presence of blood. This information sheet is designed to help you with the collection process and give you the correct information to ensure the samples you supply to the laboratory are suitable for testing. Preparation You can eat a normal diet but foods that are rich in blood such as black pudding should be avoided for three days prior to and during collection as these may give false positive results. It may be helpful to eat foods that are high in fibre to aid the passing of your stool. Some medications may cause gastrointestinal irritation, which may affect the result. If you are taking medication, ALWAYS speak to your doctor before making any changes to them. Collection of samples should be AVOIDED AT CERTAIN TIMES including: • During your menstrual period and 3 days afterwards, if you are a women. • After dental work and operations where blood loss may have occurred. • When blood is present in urine or if you have active haemorrhoids Collection You should have been given a request form and three blue faeces pots by your doctor, one to be used for each bowel movement. Please collect one sample a day for three days, rather than 3 samples during a short period of time. The likelihood of detecting any bleeding is greater over this 3day period. • • • Pass your first motion (day 1) into a clean container or into your hand covered by a small clean plastic bag. Alternatively attach some cling film across the bowl so it hangs just above the water to catch your stool. Note: It is important that the sample has not been in the toilet bowl. Using the scoop attached to the lid of the pot, take a small amount of the motion onto the scoop (about the width of a 10 pence piece), place the scoop inside the pot and secure the lid. It is important that you write the date, time of collection along with your full name and date of birth on the sample in the appropriate spaces, on the sample label. If a printed label is present on the collection pots the date and time of collection will need to be added to each sample. Patient instructions: Collecting Faecal Occult Blood Samples - Version: 1.0.

Printed: 13-Mar-2013 15:13 • • Repeat the steps above for the remaining two samples over the next two days or the next two occasions when a stool is passed (up to a maximum of 5 days). Remember to clearly label the specimen pots with your FULL NAME, D.O.B and SAMPLE COLLECTION DATES AND TIMES. The samples must be kept cool and out of direct sunlight. The samples will need to be received by the laboratory and available for analysis within 5 days of the first specimen collection. You can return the completed samples (with the request form) to your GP surgery or deliver it directly to the Pathology Laboratory. The laboratory can be accessed via the link bridge located on E level at The Queen Alexandra Hospital. Full address is detailed above. Labelling A minimum of three points of identification are required on the labels of each of the specimens (surname, forename and date of birth are essential, plus hospital number/NHS number if known – do not use initials). Inadequately labelled specimens will be rejected by the laboratory and you will be asked to produce a further series of samples.
