Peptest reflux diagnostic kits are available in a choice of two or three sample tubes. Taking two samples at the right time and according to instructions offers extremely accurate results.

However, in addition to collecting two samples when you are symptomatic, a third tube can help identify if you are prone to supine (or nocturnal) reflux. When someone suffers from supine reflux, tissue damage tends to be more severe and far more injurious than daytime reflux.

Collecting three samples will provide you with our most comprehensive testing and results service and will enable you and your doctor to tailor the treatment and management of your reflux symptoms.

To collect a sample you simply clear the throat with a cough and spit the resultant saliva into the collection tube provided, making a note of the time and any specific symptoms.

The suggested times to collect your saliva samples depend on the type of reflux symptoms you are typically suffering from but samples should always be collected on a day when you are experiencing your symptoms.

Symptoms that are usually associated with classical gastro-oesophageal reflux (GORD) or extra-oesophageal reflux (EOR) and occur at distinct times or are linked to a suspected reflux event include heartburn, hoarseness, lump in the throat, regurgitation, chronic cough, throat clearing, asthma attack, voice changes, trouble swallowing and shortness of breath.

For these symptoms, it is suggested you take your first sample within 15 minutes of experiencing reflux symptoms and a second sample after a separate reflux symptom incident that is not within an hour of the first. The third sample should be taken within 15 minutes of waking up from overnight sleep and before eating or brushing teeth, ensuring you are in an upright position.

If your symptoms are constant or with no recognisable pattern or trigger – usually associated with silent reflux (LPR) – such as sinusitis, sleep apnoea, lump in the throat, tooth decay, snoring and sore throat, then you should take your three samples as follows:

Sample one should be taken in an upright position within 15 minutes of waking up from overnight sleep before eating or brushing teeth, the second sample should be taken one hour following the main meal of the day and the third sample should be taken one hour following the next main meal of the day.

You then return your samples to the Peptest laboratory at RD Biomed for analysis and you will receive the results report within two days indicating whether each sample is positive or negative and the level of pepsin in each sample. You’ll also receive a letter addressed to your doctor explaining the results and what they mean. You should then discuss the next steps with your healthcare team as treatment will depend on your symptoms, the results of your Peptest analysis and any other relevant information.

According to our recent Peptest Customer Survey, when asked ‘What did we really do well?’ many customers hailed our ‘fast’ and ‘efficient’ service with a quick turnaround of their test results.
