Please note
There is no need to use a courier service if returning samples to the laboratory within the UK - simply use Royal Mail 1st class service or Next Day Guaranteed delivery. However, if you wish you can use the service offered by Genova Diagnostics, called Streetwise courier service. The test kit will have details of that service and the paperwork. Genova Diagnostics will charge you for this service. Current Streetwise delivery fee payable to Genova Diagnostics is £12.

DESCRIPTION

The test gives an idea of how well foods are digested and absorbed, gives some products of gut fermentation, looks for blood in the stool, gives counts of bacteria and yeast, identifies those bacteria which should not be there and gives a list of antibiotic and anti-fungal preparations, both herbal and drug, to which that micro-organism is sensitive.

The stool analysis is carried out at Genova Diagnostics in the US.

Please, note this test does not include looking for gut parasites. For that, see Comprehensive Digestive Stool Analysis with parasitology or Parasitology.

A second test, CDSA 2.0 was then designed with some markers that supersede the original CDSA. CDSA 2.0 does not report on faecal fat (measure of poor fat digestion), chymotrypsin (protein digestion) and acetates (measure of friendly fermentation). But CDSA 2.0 puts in useful additional tests, i.e.:

  • Calprotectin and EPX - these are very sensitive markers of inflammation. If these are normal then one can exclude inflammatory bowel disease as a diagnosis. Early indications suggest this is going to be an equally reliable test for bowel cancers and be an excellent screening test. Watch this space!
  • Pancreatic elastase - this is a good marker of pancreatic exocrine, ie digestive function.
  • Secondary bile acids - this is a very useful test where there is gall bladder disease, poor digestion of fats, or upper gut fermentation. A major cause of the latter is overgrowth of prevotella - see Fermentation in the gut and CFS - and prevotella is killed by bile salts (derived from bile acids).


SAMPLE

This test is performed on three stool samples.

KIT

The kit for this test includes: five collection tubes, three collection cups, detailed instructions, plastic bags for sealing the samples, a request form and an addressed envelope for returning the samples.

INSTRUCTIONS

Message from Dr Myhill:

On the instruction sheet enclosed with the kit you are advised to stop probiotics for 2 weeks prior to collecting a sample. Many of my patients take digestive enzymes or bile salts. Please, continue taking probiotics and digestive aids up to the time of collecting the sample. As long as I have a list of what you are taking, I will be able to interpret the results correctly. You will, however, need to wait for 2 weeks after stopping antibiotics and antifungals as well as anti-inflammatory medication before collecting a sample for this test.

  • Collect the samples by following the instructions enclosed with the test kit.
  • Make sure that your name, date of birth and date sample taken are correctly entered on the sample tube.
  • Make sure all the necessary details are correct on the laboratory request form.
  • Post the sample using 1st class Royal Mail service or Special Delivery Next Day service in the packaging materials provided, making sure that the laboratory request form is sent along with the samples. There is no need to use a courier service if sending samples within the UK, but if you wish you can use the one offered by Genova Diagnostics – Streetwise courier service. Current delivery fee payable to Genova Diagnostics is £12.
Please note that there is an additional interpretation fee for my letter to your GP. See Ordering Tests for more details.
