Which test requires the use of ammonia for detection of a positive result?

The test that requires the use of ammonia for detection of a positive result is the Fujiwara Test. This test is specifically designed for detecting certain types of substances, particularly in the context of drug testing. The Fujiwara Test employs ammonia as a reagent to react with the substances being analyzed, leading to a color change or other detectable phenomenon that indicates a positive result.

In this test, ammonia interacts with the substances present, often resulting in the formation of colored complexes that signify the presence of specific drugs or compounds. This characteristic is crucial for differentiating the results and confirming the presence of the targeted substance.

Understanding the role of ammonia in the Fujiwara Test enhances comprehension of how reagents are utilized in analytical methods to detect certain compounds effectively.
