What can a stool test reveal? ——Full analysis from health detection to disease early warning
In recent years, with the improvement of health awareness, fecal testing has gradually become the focus of public attention. From intestinal flora analysis to early cancer screening, stool testing technology continues to make breakthroughs, and is even dubbed by netizens as "the most honest physical examination report." This article will combine recent hot health topics with a structured analysis of the mysteries of stool testing.
1. Routine items and significance of fecal testing
| Test items | normal range | Abnormalities may prompt |
|---|---|---|
| Occult blood test | negative | Gastrointestinal bleeding, hemorrhoids, colorectal cancer |
| parasite eggs | Not detected | Roundworm/hookworm infection, amoebic dysentery |
| fat droplets | <6g/24h | Pancreatic dysfunction, malabsorption syndrome |
| pH value | 6.5-7.5 | Intestinal flora imbalance, lactose intolerance |
2. Recent hot topics: Intestinal microecological testing
According to the latest data from Baidu Health, searches for intestinal flora testing increased by 320% year-on-year. Through metagenomic sequencing technology, 3000+ species of microorganisms can be analyzed, with special attention to the following bacterial group proportions:
| Representative of beneficial bacteria | Function | Ideal proportion |
|---|---|---|
| Bifidobacteria | Enhance immunity | 15%-25% |
| Lactobacilli | Inhibit pathogenic bacteria | 5%-10% |
| Bacteroidetes | Break down dietary fiber | 20%-30% |
3. Cutting-edge breakthrough: Fecal DNA detection technology
The latest colorectal cancer screening technology approved by the US FDA has triggered heated discussions. This technology can detect the following tumor markers by detecting genetic mutations in exfoliated cells in stool:
| Gene name | mutation type | related cancers |
|---|---|---|
| KRAS | point mutation | Pancreatic/Colorectal Cancer |
| APC | deletion mutation | familial adenomatous polyposis |
| TP53 | missense mutation | Various malignant tumors |
4. Things to note before testing
1.Sampling timing: Avoid menstrual period and fast from animal blood products 3 days before the test.
2.Save requirements:Send for inspection within 2 hours or use special preservation solution
3.interference factors: Vitamin C supplements may cause false negatives for occult blood

The Weibo topic #your poop is worth 230 million times, including:
- 78% of users are concerned about intestinal flora transplant therapy
- 15% discussed the accuracy of home testing kits
- 7% shared their diagnosis and treatment experience with abnormal test results
Conclusion:Stool testing has evolved from traditional parasite examination to multi-omics joint analysis and has become an important tool in preventive medicine. Experts recommend that people over 40 years old should undergo fecal occult blood testing every year. High-risk groups can combine DNA testing technology to achieve early detection and early treatment of the disease.
