Understanding the Basics: FIT 22 and T.R.U.E. Test
What is FIT 22 by KBMO Diagnostics?
FIT 22 is an allergy testing method developed by KBMO Diagnostics. It is designed to identify allergens that may be triggering adverse immune responses in individuals. This test involves placing a small adhesive patch on the skin, which contains various allergenic substances. Over a 22-hour period, this patch releases these substances into the skin, allowing for the detection of any allergic reactions that may occur. After the designated time, the patch is removed, and any visible reactions are assessed.
One significant advantage of FIT 22 is its ability to test for a wide range of allergens simultaneously. This multiplex capability allows for a more comprehensive understanding of an individual's allergenic profile, aiding in the accurate diagnosis of specific triggers.
During the 22-hour period, the allergenic substances in the patch interact with the individual's immune system, triggering a response if the person is allergic to any of the substances. The reaction can manifest in various ways, such as redness, itching, or swelling at the site of the patch. By carefully observing and assessing these reactions, healthcare professionals can determine the specific allergens that are causing the adverse immune responses.
It is important to note that FIT 22 is a non-invasive and relatively quick testing method. The adhesive patch is easy to apply and remove, making it convenient for both patients and healthcare providers. Additionally, the ability to test for multiple allergens simultaneously reduces the need for multiple tests, saving time and resources.
An Overview of T.R.U.E. Test (Thin-layer Rapid Use Epicutaneous Test)
The T.R.U.E. Test, on the other hand, is a patch test used to identify potential allergies to various substances. It consists of a set of panels, each containing 36 patches embedded with different allergenic substances. These patches are applied to the patient's back and left in place for 48 hours. Following this period, the patches are removed, and any skin reactions are assessed.
One benefit of the T.R.U.E. Test is its broad range of allergens included in the panels, allowing for a comprehensive evaluation of potential triggers. The extended wear time of 48 hours increases the chance of detecting delayed hypersensitivity reactions, which may not be immediately apparent.
During the 48-hour period, the allergenic substances in the T.R.U.E. Test patches come into contact with the patient's skin, potentially triggering an allergic reaction. The longer wear time allows for a more thorough assessment of the individual's immune response, as some allergies may take longer to develop. This is particularly important in cases where delayed hypersensitivity reactions are suspected, as they may not be readily observable within the first few hours of exposure.
Similar to FIT 22, the T.R.U.E. Test also provides healthcare professionals with valuable information about an individual's allergenic profile. By carefully examining the skin reactions and correlating them with the specific allergens in the patches, healthcare providers can accurately identify the substances to which the patient is allergic. This information is crucial for developing personalized treatment plans and avoiding future exposure to the identified allergens.
It is worth mentioning that the T.R.U.E. Test is a widely recognized and validated method for diagnosing contact allergies. Its standardized panels and extended wear time contribute to its reliability and accuracy in identifying potential triggers. This test is particularly useful for individuals who may have experienced adverse reactions to certain substances, such as cosmetics, fragrances, metals, or medications.
The Science Behind the Tests
The Technology of FIT 22
FIT 22 by KBMO Diagnostics utilizes an innovative technology known as the LRA-MBT (Lymphocyte Response Assay - Memory B Cell Test). This method assesses the patient's immune system response to various allergens by measuring the activation of memory B cells. These cells play a vital role in the production of antibodies specific to allergenic substances.
The FIT 22 technology provides detailed information about the body's immune response, offering insights into the mechanisms of allergic reactions. This thorough analysis contributes to the accuracy of the test results, aiding in the identification of specific allergens causing adverse symptoms.
When a person comes into contact with an allergen, their immune system recognizes it as a threat and mounts a defense. This defense mechanism involves the activation of memory B cells, which are specialized white blood cells. These memory B cells have previously encountered the allergen and have stored information about it. When re-exposed to the allergen, they quickly produce antibodies that bind to the allergenic substances, preventing them from causing harm.
The FIT 22 test takes advantage of this immune response by measuring the activation of memory B cells. By analyzing the level of activation, healthcare professionals can determine the intensity of the immune response and identify the specific allergens triggering the reaction. This information is crucial in developing an effective treatment plan for individuals suffering from allergies.
How Does T.R.U.E. Test Work?
The T.R.U.E. Test operates on a different principle referred to as the patch test. It assesses the body's reaction to potential allergens by direct application to the skin. During the 48-hour wear period, allergenic substances slowly penetrate the epidermis, initiating immune responses if an allergy is present.
The T.R.U.E. Test is a widely used method for diagnosing contact dermatitis, a type of allergic reaction that occurs when the skin comes into contact with certain substances. This test is particularly helpful in identifying allergens responsible for skin rashes, itching, and other dermatological symptoms.
During the T.R.U.E. Test, a healthcare professional applies small patches containing different allergenic substances to the patient's back. These substances may include common allergens such as nickel, fragrance mix, and rubber accelerators. The patches are left in place for 48 hours, allowing the allergenic substances to slowly penetrate the skin. If the patient is allergic to any of the substances, an immune response will be triggered, resulting in visible reactions.
After the 48-hour wear period, the patches are removed, and the healthcare professional examines the skin for any signs of allergic reactions. These reactions may manifest as redness, swelling, or itching. By carefully analyzing the skin's response, healthcare professionals can identify the specific allergens causing the symptoms.
The T.R.U.E. Test is a convenient and non-invasive method for diagnosing contact dermatitis. It provides valuable information that helps individuals avoid allergenic substances and manage their symptoms effectively.
Comparing FIT 22 and T.R.U.E. Test
Accuracy and Reliability
Both FIT 22 and T.R.U.E. Test have demonstrated high levels of accuracy and reliability in detecting allergenic triggers. However, their methods of assessment differ. FIT 22 assesses the immune system's memory B cell response, providing detailed information on specific allergens. This method involves analyzing the production of antibodies by memory B cells, which are specialized immune cells that "remember" previous encounters with allergens. By measuring the levels of specific antibodies in the blood, FIT 22 can identify the allergens to which an individual's immune system has developed a response.
Conversely, T.R.U.E. Test relies on visual observation of skin reactions, allowing for a broader assessment of potential allergens included in the test panels. This method involves applying small patches containing different allergens to the patient's skin and monitoring for any signs of an allergic reaction. The patches are typically left on the skin for a specific period of time, and the healthcare professional then evaluates the skin's reaction to determine the presence of allergies.
It is important to note that the accuracy and reliability of both tests may be influenced by individual factors such as the patient's immune system and the presence of any medications that could affect immune responses. Additionally, the interpretation of test results should be done by qualified healthcare professionals who can consider the patient's medical history and symptoms.
