If you searched “stool test,” you probably want clarity
Most people are not looking for a specific lab name. They’re asking:
- What does this stool mean?
- Is this normal?
- Do I need to worry?
That’s why it helps to separate two paths.
You can use a medical lab test to answer a specific clinical question. Or you can use tracking to understand what’s been happening in real life (and bring better info to a clinician if you need to).
Option 1: clinical stool tests (medical)
Clinical stool tests are used to answer a specific medical question. They’re best when you and a clinician agree on the question you’re trying to answer.
A) Screening (you feel well)
These are for average-risk screening, not for interpreting day-to-day variability.
Common stool-based screening options include:
- FIT
- High-sensitivity gFOBT
- Stool DNA tests (multitarget stool DNA with a FIT component)
If a stool-based screening test is abnormal, follow-up with colonoscopy is typically needed.
B) Symptom workup (you have symptoms)
If you have symptoms, tests are usually ordered to narrow down causes:
- Infection (stool PCR panels, culture, parasite testing, C. diff)
- Inflammation (fecal calprotectin)
- Bleeding (FIT/FOBT in a workup context)
- Malabsorption / digestion (fecal fat, fecal elastase in the right context)
What these tests don’t do is explain every day-to-day change in stool appearance. A normal test doesn’t always answer “why does my poop look different this week?”

Option 2: understand your poop with tracking (educational)
If your goal is to understand your poop, tracking is often the most direct path. A lab test is useful when you’re asking a specific medical question. Tracking is useful when you’re asking: “What keeps changing, and what seems to drive it?”
Tracking helps you answer questions like:
- Is this a one-off change, or a pattern?
- Does it line up with certain foods, caffeine, alcohol, travel, stress, or antibiotics?
- Is it mostly color, mostly consistency, or both?
Where StoolSense fits
StoolSense is built for tracking, not diagnosis. It helps you label what you’re seeing consistently so patterns are easier to spot and explain.
With StoolSense you can:
- Log manually (Bristol type + color)
- Or take a photo and let AI suggest tags (Bristol type + color) so you don’t have to guess every time
- Add quick context (time of day, urgency/pain, and a possible driver)
You always review and edit before saving. This is educational and not medical advice.
If you want a simple way to use it:
- Track for 7 days
- Look for repeats (same color/consistency at the same time of day, after the same foods, during stress, etc.)
- If you decide to see a clinician, bring the summary instead of trying to remember details

How to choose quickly
- If you have red flags, do not wait: seek medical care.
- If symptoms are persistent, severe, or getting worse, consider clinical evaluation and targeted testing.
- If you’re trying to understand patterns (timing, diet triggers, consistency), track for 7 days first.
What to track for 7 days (copy/paste)
- Bristol type + color + time of day
- Frequency
- Any blood (bright red vs dark/maroon vs black/tarry)
- One symptom if relevant (urgency or pain)
- Recent antibiotics, travel, big diet changes
What to bring to an appointment (copy/paste)
- When it started and whether it is improving or worsening
- Stool frequency + Bristol type + color
- Any blood (bright red vs dark vs black/tarry)
- Symptoms (pain, fever, urgency, dizziness, weight loss)
- Recent antibiotics, travel, sick contacts
- Meds/supplements (NSAIDs, blood thinners, iron, bismuth/Pepto)
When to escalate urgently
Seek urgent care for large amounts of blood, clots, black/tarry stool, faintness, severe pain, high fever, confusion, or signs of dehydration.
