If you’ve stumbled upon the term “Becher Test,” you might wonder what it refers to. Is it a scientific experiment? A measure of something cultural? Or is it simply a misunderstood concept? The truth is, the term “Becher Test” is often a misnomer or misremembered, frequently used to refer to one of three distinct ideas:
- The Bechdel Test evaluates women’s representation in fiction.
- The Xanthoproteic Test is a biochemical test for detecting aromatic amino acids.
- Becher’s Reaction, an outdated biochemical test for assessing kidney function.
Each of these serves a unique purpose in its field, from media studies to biochemistry. This blog will dissect these concepts, clarify their meanings, and explore the possible confusion surrounding them.

The Bechdel Test Explained
What is the Bechdel Test?
The Bechdel Test is a tool used to analyze the representation of women in fiction, including films, TV shows, and books. Its purpose is to spotlight patterns of female underrepresentation in media and assess whether women are portrayed in meaningful, substantive ways.
How it Works
To pass the Bechdel Test, a work of fiction must meet three simple criteria:
- It must feature at least two named female characters.
- These characters must have a conversation.
- The conversation must be about something other than a man.
Though straightforward, this test often reveals how frequently women are sidelined in storytelling, with many popular works failing to meet the criteria.
Not a Measure of Quality
It’s essential to note that while the Bechdel Test highlights the lack of representation, it is not a measure of a work’s quality or worth. A movie can fail the test and still be highly regarded, while a film that passes isn’t automatically progressive or well-made. The test merely provides a lens to examine female representation.
Origins of the Bechdel Test
The Bechdel Test was first introduced in the 1985 comic strip “Dykes to Watch Out For” by Alison Bechdel. Though she credited her friend Liz Wallace with the idea, it has since become a widely recognized standard for analyzing gender dynamics in media.
The Xanthoproteic Test Explained
What is the Xanthoproteic Test?
The Xanthoproteic Test is a biochemical procedure used to identify the presence of aromatic amino acids, such as tyrosine, tryptophan, and phenylalanine. These amino acids are crucial components of proteins and serve essential functions in biological systems.
The Method
The test relies on a chemical reaction involving concentrated nitric acid:
- Add focused nitric acid to the sample being tested.
- Observe any color change to yellow, which indicates the presence of aromatic amino acids.
- To enhance the yellow coloration, the solution can be neutralized with a base.
This specific color change is due to the reaction between aromatic rings in the amino acids and nitric acid, forming xanthoproteic acid.
Applications in Biochemistry
The Xanthoproteic Test helps researchers and biochemists identify protein composition and amino acid content in a given sample. It’s an elegant demonstration of how specific chemical reactions can highlight particular molecular structures.
Becher’s Reaction
What is Becher’s Reaction?
Becher’s reaction, sometimes confused with the Xanthoproteic Test, is a specialized biochemical reaction tailored for medical purposes. It targets aromatic nitrogenous substances in blood serum and has historical significance in evaluating kidney function.
The Method
To perform Becher’s Reaction:
- Use de-albumenized blood serum (removing proteins from the blood sample).
- Add concentrated nitric acid to the serum.
- Observe the resulting reaction. A positive test produces a distinct yellow color.
This color change indicates the presence of aromatic nitrogenous substances, which are often elevated in cases of severe kidney dysfunction, such as chronic uremia.
Clinical Significance
Historically, Becher’s reaction was used as an early diagnostic tool for assessing kidney function. A stronger reaction indicated a higher concentration of these substances, signaling potential renal issues.
However, it’s important to note that Becher’s reaction is not a definitive diagnostic method and has been largely replaced by modern, more accurate medical tests.
Clearing the Confusion
The term “Becher Test” can be perplexing, mainly because it doesn’t refer to a single, clearly defined test. Instead, it frequently serves as an umbrella term or misnomer for:
- The Bechdel Test and its focus on gender representation in media.
- The Xanthoproteic Test is a biochemical method of detecting aromatic amino acids.
- Becher’s Reaction, an outdated medical procedure related to kidney function.
Understanding the context in which the term is used is key to discerning the intended meaning and purpose.
FAQs About the Becher Test
Is the Bechdel Test universal for all media?
It is widely applicable to various forms of fiction but is specifically designed to highlight gender representation issues in storytelling.
What’s the main difference between the Xanthoproteic Test and Becher’s Reaction?
The Xanthoproteic Test identifies aromatic amino acids in any protein sample, while Becher’s Reaction adapts this test to focus on blood serum as part of kidney function studies.
Is Becher’s reaction still used in modern medicine?
No, Becher’s reaction is considered obsolete. Modern diagnostic technology offers more precise and reliable methods for assessing kidney function.
Does passing the Bechdel Test make a movie feminist?
Not necessarily. Passing the Bechdel Test only demonstrates basic representation. A feminist narrative involves deeper, more complex portrayals of gender equality.
Why do people confuse these tests?
The term “Becher Test” likely arises from phonetic similarities or linguistic misunderstandings. Its usage spans vastly different fields, leading to frequent confusion.
