A rapid test for the qualitative detection of Acet/aminophen in human urine. For medical and other professional in vitro diagnostic use only.
The ACE Rapid Test Cassette (Urine) is a rapid chromatographic immunoassay for the detection of Aceta/minophen in human urine at a cut-off concentration of 5,000ng/mL. This assay provides only a qualitative, preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) or Liquid Chromatography/mass spectrometry (LC/MS) are the preferred confirmatory methods. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminar positive results are used.
Acetaminoph/en is one of the most commonly used drugs, yet it is also an important cause of serious liver injury. Acetamin/ophen is the generic name of a drug found in many common brand name over-the-counter (OTC) products, such as Tylenol, and Prescription (Rx) products, such as Vicodin and Percocet. Acetam/inophen is an important drug, and its effectiveness in relieving pain and fever is widely known. Unlike other commonly used drugs to reduce pain and fever (e.g., nonsteroidal antinflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen), at recommended doses acetami/nophen does not cause adverse effects, such as stomach discomfort and bleeding, and acetamin/ophen is considered safe when used according to the directions on its OTC or Rx labeling. However, taking more than the recommended amount can cause liver damage, ranging from abnormalities in liver function blood tests, to acute liver failure, and even death. Many cases of overdose are caused by patients inadvertently taking more than the recommended dose (i.e., 4 grams a day) of a particular product, or by taking more than one product containing acetamin/ophen (e.g., an OTC product and an Rx drug containing acetami/nophen).
The mechanism of liver injury is not related to acetam/inophen itself, but to the production of a toxic metabolite. The toxic metabolite binds with liver proteins, which cause cellular injury. The ability of the liver to remove this metabolite before it binds to liver protein influences the extent of liver injury.
The ACE Rapid Test Cassette (Urine) is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of Acetam/inophen in urine. The ACE Rapid Test Cassette (Urine) yields a positive result when Aceta/minophen in urine exceeds 5,000ng/mL.
The ACE Rapid Test Cassette (Urine) is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody.
During testing, a urine specimen migrates upward by capillary action. Acetamin/ophen, if present in the urine specimen below 5,000ng/mL, will not saturate the binding sites of antibody-coated particles in the test. The antibody-coated particles will then be captured by immobilized Acetami/nophen conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the Acetam/inophen level exceeds 5,000ng/mL because it will saturate all the binding sites of anti-Aceta/minophen antibodies.
A drug-positive urine specimen will not generate a colored line in the test line region because of drug competition, while a drug-negative urine specimen or a specimen containing a drug concentration lower than the cut-off will generate a line in the test line region. To serve as a procedural control, a colored line will always appear in the control line region, indicating that proper volume of specimen has been added and membrane wicking has occurred.
The test contains mouse monoclonal anti-Aceta/minophen antibody-coupled particles and Acetamin/ophen-protein conjugate. A goat antibody is employed in the control line system.
• For medical and other professional in vitro diagnostic use only. Do not use after the expiration date.
• The test should remain in the sealed pouch until use.
• All specimens should be considered potentially hazardous and handled in the same manner as an infectious agent.
• The used test should be discarded according to local regulations.
STORAGE AND STABILITY
Store as packaged in the sealed pouch either at room temperature or refrigerated (2-30°C).
The test is stable through the expiration date printed on the sealed pouch. The test must remain in the sealed pouch until use. DO NOT FREEZE. Do not use beyond the expiration date
DIRECTIONS FOR USE
Allow the test, urine specimen, and/or controls to reach room temperature (15-30°C) prior to testing.
1. Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it within one hour.
2. Place the test cassette on a clean and level surface. Hold the dropper vertically and transfer 3 full drops of urine (approx. 120 µL) to the specimen well (S) of the test cassette, and then start the timer. Avoid trapping air bubbles in the specimen well (S). See the illustration below.
3. Wait for the colored line(s) to appear. Read results at 5 minutes. Do not interpret the result after 10 minutes.
INTERPRETATION OF RESULTS
(Please refer to the illustration above)
NEGATIVE:* Two distinct colored lines appear. One colored line should be in the control line region (C), and another apparent colored line should be in the test line region (T). This negative result indicates that the Aceta/minophen concentration is below the detectable level (5,000ng/mL).
*NOTE: The shade of color in the test line region (T) will vary, but it should be considered negative whenever there is even a faint colored line.
POSITIVE: One colored line appears in the control region (C). No line appears in the test line region (T). This positive result indicates that the Acet/aminophen concentration exceeds the detectable level (5,000ng/mL).
INVALID: Control line (C) fails to appear. Insufficient specimen volume or incorrect procedural techniques are the most likely reasons for control line failure. Review the procedure and repeat the test using a new test. If the problem persists, discontinue using the lot immediately and contact your local distributor.
A procedural control is included in the test. A colored line appearing in the control region (C) is considered an internal procedural control. It confirms sufficient specimen volume, adequate membrane wicking and correct procedural technique.
Control standards are not supplied with this kit; however it is recommended that positive and negative controls be tested as good laboratory practice to confirm the test procedure and to verify proper test performance
