diagnostic tests for GI disrders
The document provides information on various diagnostic tests for gastrointestinal disorders. It discusses tests for gastroesophageal reflux disease (GERD) including ambulatory pH monitoring, endoscopy, esophageal manometry, and barium X-ray. Tests for esophagitis are described as barium X-ray and endoscopy. Laboratory tests for esophagitis include histology. Tests for stomach disorders like peptic ulcer and gastritis caused by Helicobacter pylori include endoscopic tests, histology, culture, molecular testing like PCR, and indirect endoscopic tests like the urease test. Serological tests and stool antigen tests are also discussed.
H pylori
Helicobacter pylori is a bacteria that causes peptic ulcers and is linked to gastric cancer. There are invasive and non-invasive tests to diagnose H. pylori infection. Invasive tests include histology, culture, and rapid urease test, while non-invasive options are urea breath test, stool antigen test, and serology. Molecular techniques like PCR are also used and can identify specific genes or antibiotic resistance. The accuracy of diagnostic tests may be affected in cases of bleeding or partial gastrectomy. Post-treatment tests like urea breath test are recommended to confirm eradication success.
A gastric or stomach ulcer is regularly caused by an infection with .pdf
A gastric or stomach ulcer is regularly caused by an infection with bacterium Helicobacter pylori
(H. pylori) and long-term use of non-steroidal anti-inflammatory drugs (NSAIDs), such as
ibuprofen and aspirin.
1. To detect an ulcer, first take a consideration of pre-medical history and execute a physical
exam.
2. Laboratory tests for H. pylori :
Blood tests are normally inaccurate and should not be regularly used and the breath test is the
most accurate.
For the breath test, eat or drink something containing radioactive carbon. H. pylori break down
the material in the stomach. Later, blow into a bag, which is then sealed. If infected with H.
pylori, your breath sample will contain the radioactive carbon in the form of carbon dioxide.
Endoscopy was used to examine the upper digestive system. During endoscopy, passes a hollow
tube equipped with a lens of endoscope down to throat and into esophagus, stomach and small
intestine. This endoscope had revealed the ulcers in the stomach.
If detects an ulcer, small tissue samples may be removed for examination in a lab for biopsy test.
A biopsy also identify whether H. pylori is in the stomach lining.

Escherichia coli is the most common cause of urinary tract infections (UTIs). UTIs can present as cystitis, pyelonephritis, or urosepsis. Laboratory diagnosis of UTIs involves collecting a urine sample and testing for significant bacteriuria, typically over 104 colony forming units per mL. Urine culture and sensitivity testing can identify the causative organism and determine appropriate antibiotic treatment.

Methods of detection of Helycobacter.pptx
- 1. Methods of detection of Helicobacter pylori Naimenur KORKMAZ 4th course 2nd group
- 2. What is helicobacter pylori? • Helicobacter pylori is a type of bacteria that infects the lining of the stomach and upper intestine. • It's spiral-shaped and is known to be a major cause of various gastrointestinal disorders, including gastritis (inflammation of the stomach lining) and peptic ulcers (sores in the lining of the stomach or duodenum). • H. pylori is primarily transmitted through oral-oral or fecal-oral routes. • It's estimated that over half of the world's population is infected with this bacterium, though not everyone who is infected will develop symptoms or complications. • There are several methods to detect the presence of H. pylori in a person. These methods include:
- 3. BLOOD TESTS • Serology: This test looks for antibodies in the blood that the body produces in response to an H. pylori infection. However, it's worth noting that serology tests can remain positive even after the bacteria have been eradicated.
- 4. STOOL TESTS • Antigen Tests: These tests detect H. pylori proteins in a stool sample. They are a reliable way to confirm the presence of the bacteria and monitor the effectiveness of treatment.
- 5. UREA BREATH TEST • In this test, the patient swallows a capsule or liquid that contains a special type of urea labeled with a radioactive or non-radioactive marker. If H. pylori is present, it will break down the urea and release the marker, which can be detected in the breath.
- 6. ENDOSCOPY • Biopsy: During an endoscopy, a thin, flexible tube with a camera at the end is passed through the mouth and into the stomach. If H. pylori is suspected, the doctor will take small tissue samples (biopsies) from the lining of the stomach for analysis. These biopsies are then examined under a microscope to check for the presence of H. pylori.
- 7. RAPID UREASE TEST • A small sample of tissue from the stomach lining is taken during an endoscopy and placed in a special solution that contains urea. If H. pylori is present, it will produce an enzyme (urease) that breaks down the urea, leading to a change in the color of the solution.
- 8. PCR (POLYMERASE CHAIN REACTION) • PCR is a molecular biology technique that amplifies specific DNA sequences. It can be used to detect the DNA of H. pylori in samples taken from the stomach lining.
- 9. CULTURES • Culturing involves taking a sample from the stomach lining and attempting to grow H. pylori in a laboratory. This method is less commonly used due to its complexity and the time it takes to obtain results. • Histology: • This involves examining tissue samples under a microscope to look for signs of H. pylori infection, such as inflammation and bacterial presence.
