Hiatal hernia. A hiatal hernia occurs when the upper part of your stomach bulges through your diaphragm into your chest cavity. A hiatal hernia occurs when the upper part of your stomach bulges through the large muscle separating your abdomen and chest (diaphragm). Your diaphragm has a small opening (hiatus) through which your food tube (esophagus) passes before connecting to your stomach. In a hiatal hernia, the stomach pushes up through that opening and into your chest.

Sensitivity is the ability of a test to correctly identify individuals who have a given disease or condition. For example, a certain test may have proven to be 90% sensitive. If 100 people are known to have a certain disease, the test that identifies that disease will correctly do so for 90 of those 100 cases (90%).The other 10 people (10%) tested will not show the expected result for this test.For that 10%, the finding of a normal result can be misleading and is termed false-negative.he accuracy and precision of each test method are established and are frequently monitored by the professional laboratory personnel. Sensitivity and specificity data are determined by research studies and are generally found in medical literature.
