What is a Nitrazine Test?
A Nitrazine Test is a diagnostic screening tool used to measure pH levels in fluids. Nitrazine paper changes color depending on the acidity or alkalinity of the tested sample, making it useful for identifying pH imbalances or the presence of specific bodily fluids.
Nitrazine testing is commonly used in healthcare settings because it delivers quick visual results without requiring complex laboratory equipment. The color change produced by the test helps healthcare professionals make rapid assessments when time-sensitive decisions are necessary.
How Does Nitrazine Testing Work?
Nitrazine tests use specially treated paper or strips that react to pH levels. When exposed to a specimen, the strip changes color based on whether the sample is acidic, neutral, or alkaline.
Different pH levels correspond to different color ranges, allowing for easy visual interpretation. Proper specimen collection and accurate timing are important to ensure dependable results.
How to Use a Nitrazine Single Dip Test:
Nitrazine Test Instructions:
Remove the Nitrazine Single Dip Test from its sealed packaging and use immediately for best results.
Carefully handle the test strip by the end opposite the testing area to avoid contamination.
Dip the testing portion of the strip into the specimen briefly, ensuring the reactive area is fully exposed to the sample.
Remove the strip and compare the resulting color change to the provided color chart or interpretation guide.
Read and interpret results immediately according to the product instructions. Delayed readings may affect accuracy.
Dispose of the used test properly after use.
How to Read a Nitrazine Single Dip Test?
Alkaline Result

- Reasonable-suspicion or reasonable-cause testing
- Post-accident testing
- Return-to-duty workplace testing
- Insurance-related screening
An Employment & Insurance designation does not automatically apply to every FUO product or every drug-testing product sold by 12 Panel Now.
The specific labeling and intended use of the individual product controls.
5. FEDERAL DRUG-TESTING PROGRAMS
Employment & Insurance products must not automatically be assumed to satisfy the requirements of federally regulated drug-testing programs.
Unless the particular product and testing methodology are authorized for the applicable program, customers must not assume that a general Employment & Insurance drug test is appropriate for federally regulated programs including those involving:
- S. Department of Transportation (DOT)
- Substance Abuse and Mental Health Services Administration (SAMHSA)
- S. Military
- Other federal drug-testing programs having specific regulatory requirements
Customers performing federally regulated testing are responsible for ensuring that the specimen type, collection process, chain-of-custody procedures, laboratory testing, confirmatory testing, Medical Review Officer requirements, reporting and other elements of the testing program comply with applicable federal requirements.

What Shows Up as AMP on a Drug Test?
Drug tests detect amphetamines by looking for the presence of the drug or its metabolites. In the case of amphetamines, one primary metabolite is amphetamine itself, and another is 4-hydroxyamphetamine. Most often, immunoassay screening tests are used first, which are highly sensitive but not highly specific. If this test is positive, then a confirmatory test using a method like gas chromatography/mass spectrometry (GC/MS) or liquid chromatography/mass spectrometry (LC/MS) is often used, which is both highly sensitive and highly specific. These tests can distinguish amphetamine from other substances that might cause a false positive on the screening test.
How long after use can amphetamines be detected in an AMP Drug Test?
The detection window for amphetamines depends on several factors including the type of drug, the frequency and amount of use, the individual's metabolism, and the type of test used. However, generally, amphetamines can be detected in urine for 1-3 days after use, in blood for about 12-24 hours, in saliva for 1-2 days, and in hair for up to 90 days.
What Is the Difference Between Amphetamine and Methamphetamine?
An amphetamine is a prescription drug stimulant such as Adderall. It is similar to methamphetamine or meth in that both create a ‘high’ or a feeling of euphoria. However, meth is illegal. It works much faster in the brain than methamphetamine; thus, users prefer the former to get the ‘high’ feeling more quickly.
Can an AMP Drug Test return false positives?
Yes, although it's rare, an Amphetamine Drug Test can return a false positive. Some over-the-counter medications, certain prescription drugs, and even some foods may cause a false positive result. If you believe your test result is a false positive, you should communicate this to the testing administrator and request a confirmatory test, such as a gas chromatography-mass spectrometry (GC-MS) test.
What are the consequences of a positive Amphetamine Drug Test?
The consequences of a positive AMP Drug Test depend on the context in which the test was administered. In a workplace setting, it may lead to disciplinary action, including potential termination. In a legal context, it could impact parole, custody cases, or other court-related matters. In a medical setting, it might necessitate changes to a treatment plan.
Can prescription medications lead to a positive Amphetamine Drug Test?
Yes, prescription medications that contain amphetamines, such as Adderall, used for treating attention deficit hyperactivity disorder (ADHD), can cause a positive result on an AMP Drug Test. If you're taking a prescription medication, it's essential to disclose this information prior to the test to prevent any misinterpretation of results.

All Orders Will Be Shipped the Same Day If Placed Before 3:00 PM EST.
Next-day Shipments Will Not Be Delivered on Weekends, and That the Time Taken on Air Shipments Should Be Counted as Business Days.

Why Does My Tracking Info Still Say "Label Created, Not yet in the System" When I Placed It X Days Ago?
If your order was placed via USPS, sometimes your label might not show up in their system even 1-3 days after they have received the package. The same can happen for UPS orders, although they almost always show up in their system the night which they are shipped. If you have any questions regarding the status of your order, please contact us and we will investigate the matter.
If I Pay for a next Day Air Delivery, Am I Guaranteed to Receive It the next Day?
Air deliveries performed by UPS are counted via business days, so you will receive your package the business day after it has been shipped. We also do not ship orders placed after 4 pm EST on the same day, so Next Day orders placed after 4 pm will be shipped the following business day.
Why Can't I Check the Tracking of My Package?
After you place your order, an email will be sent to you with the tracking number within a business day. If you did not receive this email, it's possible that the e-mail was entered incorrectly, sent to your spam folder, or blocked. If you did not receive this email, please call or email us and we'll be happy to give you the status of your shipment.
I Placed My Order but I No Longer Need It. Can I Return It and Get a Refund?
We accept returns for unused items as long as they are placed within 30 days after the day they are purchased. Although shipping is free upon order, we still incur a cost for every order that is shipped, and you will be refunded the amount of your order once we receive the returned goods, minus the cost of shipping.
