What does a poo sample test for?

Greetings readers, and welcome to an informative yet hopefully comical journey into the nether regions of medical diagnostics – your poo sample. You may be wondering: what the heck is the point of a fecal exam? Why on earth would anyone want to test samples of poop?! Well, my curious friends, hold onto your britches (literally), because we’re about to dive in and explore this brown and stinky world.

Why Get Your Poop Tested?

Before we get into all of the gross details (and trust me, there will be plenty), let’s start with why you might actually need to have your poop examined by professionals. Here are just a few reasons:

  • Gastrointestinal Issues: If you’ve been experiencing symptoms like diarrhea or constipation for longer than usual or have noticed any sudden changes in bowel habits, stool testing can help identify underlying conditions.
  • Screening for Intestinal Parasites: Ingested parasites can wreak havoc on our gastrointestinal tracts without us even realizing it. However, detecting these unwanted guests early on via stool exams is crucial for effective treatment.
  • Monitoring Digestive Health: Getting regular checkups that include fecal sampling can help health care providers monitor overall digestive tract health as well as track progress post-treatment.

The Types of Tests Conducted

Now that we know some reasons why someone might request a number 2 analysis from their doctor let’s examine what kind of tests one might expect when producing faecal matter at said appointment:

Culture Tests

Culture tests are used if bacteria levels are suspectedly too high/low/infection-related inside or near digestive tissues; doctors will distribute whatever arrives in front them from rectally-produced specimens through Petri culture plates under specific environmental protocols that enable growth indicators alongside identification methods after colonies manifest over days

Ova & Parasite Exam

“Yay, parasites! That’s what I always wanted!” said no one ever. However, parasites can and do infect human digestive systems- and the only reliable way to diagnose this is through very exciting microscopic analysis of fecal matter under a microscope by lab technicians.

Occult Blood Test

This type of study is typically done as part of colorectal cancer screening or when blood in stool indicating a disease source unknown becomes noticed. Healthcare providers take the poo sample yet apply different reagents during processing that will demonstrate presences of tiny concentrations relating to hemoglobin compounds.

What Can Be Diagnosed via Stool Sample Analysis?

Nope, we’re not done talking about poop just yet. Here are some conditions health care professionals MAY make diagnoses for after examining your faecal sludge:


Bacterial infections such as Campylobacteriosis, Salmonellosis – amongst many others- have observable symptoms like diarrhea and abdominal pain; so physicians use tests that check specific bacteria proteins/dna content related to corresponding diseases.


Parasitic infestations such as Giardiasis or Cryptosporidium mainly spread through bad water sources but may be contracted from infected people handling food improperly too – sterile techniques are important with all samples taken!

Digestive Issues:

Digestive issues most often relate to lackluster pancreas secretions (aiding in digestion) production producing guest stomach distress causing tummy troubles requiring confirmation via medical examinations.

Colorectal Cancer Detection

Our feces products can tell tales about our colons’ health regarding cellular growth – either destroying cells multiplication rates increasing / changing how they align with other cells also any rectal bleeding evidence found requires further testing.

In Conclusion

Hopefully now you have a better understanding of what goes on behind the scenes when it comes to fecal exams. So next time someone tells you they need to give their poo sample, you can nod your head knowingly and say “ah yes, for bacterial identification purposes no doubt”. And remember: not all heroes wear capes- some of them work in lab coats and have the unenviable job of sifting through poop samples to help keep us all healthy.
