What is TCA?
TCA stands for tricyclic antidepressants. This prescription drug is often recommended as the treatment of depression and treatment for major depressive disorder (MDD).
Tricyclic Antidepressants
Tricyclic Antidepressant (TCA) were one of the first antidepressants released. Today, they are still available and widely used for treating depression.
Though they aren’t considered as addictive as other prescription medications, long-term Tricyclic Antidepressant (TCA) usage can, unfortunately, lead to dependency.
Tricyclic Antidepressant (TCA) abuse is a concern among many in the United States today. For this reason, many urine tests and multidrug tests contain drug panels that detect TCA’s as many incorporate screening for this drug into their drug testing procedures.
How to Use a Tricyclic Antidepressant (TCA) Drug Test:
TCA Drug Test Instructions:
- Remove the Tricyclic Antidepressant (TCA) drug test from its sealed pouch and use it as soon as possible. For best results, perform the test within an hour.
- Next, hold the test by the end, where you can see the product name. To avoid contamination, do not touch the test membrane.
- Then, holding the test vertically, dip the test in the urine specimen for at least 10-15 seconds. Do not immerse above the maximum line (MAX) on the test. That’s about 1/5th of the way up the test.
- After the drug test has finished, remove the test from the specimen and place it on a non-absorbent flat surface. Start the timer and wait for the colored band(s) to appear. Read the result at 5 minutes. Do not interpret it after 10 minutes.
How to Read A Tricyclic Antidepressant (TCA) Test?
Positive
Only one colored band appears, in the control region ©. No apparent colored band appears in the test region (T)
Negative
Two colored bands appear on the membrane. One brand appears in the control regions © and another band appears in the test region (T).
Invalid
Control band fails to appear. Results from any test which has not produced a control band at the specified read time must be discarded. Please review the procedure and repeat with a new test. If the problems persist, discontinue using the kit immediately and contact your local distributor.

1. FORENSIC USE ONLY PRODUCTS
Products labeled FORENSIC USE ONLY (FUO) are not intended to be used or represented as FDA-cleared clinical diagnostic devices when they do not possess such clearance.

Appropriate users and settings may include:
- Court systems
- Police departments
- Law-enforcement agencies
- Probation departments
- Parole departments
- Juvenile detention facilities
- Prisons
- Jails
- Correctional facilities
- Appropriate governmental agencies

- Other establishments performing forensic testing on behalf of qualifying law-enforcement, correctional, judicial or governmental entities
Products designated Forensic Use Only should be used only in accordance with their applicable labeling and intended use.
2. NOT FOR CLINICAL DIAGNOSIS
A product designated Forensic Use Only is not intended to diagnose, treat, prevent, monitor or identify a disease, illness, medical condition or drug dependency.
An FUO designation must not be represented by a purchaser, reseller or distributor as equivalent to FDA clearance for clinical diagnostic use.
3. AT-HOME AND OVER-THE-COUNTER USE
Unless the particular device is specifically cleared, authorized and labeled for home or Over-the-Counter use, a product labeled Forensic Use Only is not intended to be marketed or sold as a consumer At-Home or OTC diagnostic product in the United States or its territories.
Customers, distributors and resellers are responsible for maintaining the intended-use designation when advertising or redistributing these products.
4. EMPLOYMENT & INSURANCE PRODUCTS
Certain drugs-of-abuse testing devices may be specifically labeled for Employment & Insurance testing.
Where permitted by the specific product’s labeling and regulatory status, Employment & Insurance applications may include certain:
- Pre-employment testing
- Workplace testing
- Random workplace testing
- 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.
6. SPECIALTY AND EMERGING DRUG TESTS
12 Panel Now carries standard and specialty drug-testing configurations.
Depending upon the particular product, labeling, configuration and regulatory status, products testing for certain specialty or emerging analytes may be designated Forensic Use Only or possess another restricted intended use.
Examples may include products screening for:
- Fentanyl (FEN)
- Xylazine (XYL)
- Tianeptine / ZaZa (TIA)
- Kratom (KRA)
- Synthetic Marijuana / K2 / Spice
- Ethyl Glucuronide / EtG
- Alcohol (ALC)

- Methaqualone (MQL)
- MDPV / certain synthetic cathinones sometimes referred to as Bath Salts
- Psilocybin / mushroom-related screening configurations
- Other emerging or non-standard drug analytes
The appearance of an analyte on this list does not mean that every test containing that analyte is automatically classified as Forensic Use Only.
Different products testing for the same substance may possess different regulatory classifications.
Always follow the regulatory designation and intended-use labeling of the specific product.
7. FENTANYL PRODUCTS
Fentanyl testing products are available in different formats and may possess different intended uses and regulatory classifications.
Customers should therefore not assume that all fentanyl test strips, cups, dip cards, cartridges or other fentanyl-testing devices have the same regulatory status simply because they detect fentanyl.
The designation applicable to the particular product controls.
8. ORAL FLUID AND SALIVA TESTING
Certain oral-fluid or saliva drug-testing devices and configurations may be designated Forensic Use Only or have other intended-use restrictions.
The regulatory status of a urine-testing device must not be assumed to apply to an oral-fluid device, or vice versa, merely because both devices test for similar substances.
Customers should verify the designation applicable to the specific oral-fluid product.
9. RAPID TESTS PROVIDE SCREENING RESULTS
Unless the applicable product labeling expressly provides otherwise, rapid drugs-of-abuse tests are screening devices.
A preliminary positive, presumptive positive or non-negative screening result should not automatically be regarded as a definitive laboratory-confirmed result.
Where confirmation is required by law, regulation, employer policy, court procedure, correctional policy, insurance program or other applicable standard, confirmatory laboratory testing should be performed using an appropriate confirmatory methodology.
10. COLLECTION AND CHAIN OF CUSTODY
Organizations using drug-testing devices are responsible for implementing collection and handling procedures appropriate for their program.
Depending upon the application, this may include:
- Donor identification
- Specimen integrity procedures
- Chain-of-custody documentation
- Secure specimen handling
- Result documentation
- Laboratory confirmation
- Medical Review Officer review
- Record retention
- Confidentiality
- Reporting procedures
12 Panel Now supplies testing products but does not control the customer’s testing program or individual testing procedures.
11. PRODUCT INSTRUCTIONS CONTROL
Customers must follow all applicable manufacturer instructions, package inserts, cutoff information, warnings, limitations and interpretation requirements.
Website descriptions and general educational information do not replace the official labeling and instructions applicable to the individual device.
12. NO MEDICAL DIAGNOSIS
Rapid screening products should not be used as substitutes for medical diagnosis, clinical evaluation or appropriate laboratory confirmation where such services are necessary.
12 Panel Now does not diagnose medical conditions, substance-use disorders or drug dependency through the sale of a testing device.

- The intended application
- The intended testing program
- The intended end user
- The applicable jurisdiction
- The type of specimen being tested

- Make unsupported medical or diagnostic claims
- Change or misrepresent the intended use
- Make regulatory claims not authorized by the applicable product labeling
Resellers remain responsible for independent claims or representations they make to their customers.
15. REGULATORY STATUS MAY DIFFER BETWEEN PRODUCTS

For this reason, customers should never assume regulatory status based solely upon:
- The number of panels
- Analytes detected
- Product appearance
- Product name
- Cup design

The specific product’s regulatory status and labeling controls.

Why Are Tricyclic Antidepressants on a Drug Test?
Tricyclic antidepressants (TCAs) are included in some drug tests because they can help determine cases of toxicity, overdose, and other emergencies. TCA can also cause false positive results for other drugs, such as cocaine. A TCA screen may be ordered by a healthcare provider to ensure that a patient is receiving a safe and effective dose of a TCA medication or to diagnose a TCA overdose, which can cause symptoms such as dry mouth, blurred vision, constipation, trouble urinating, drowsiness, lightheadedness, and seizures. TCAs are a class of antidepressants that affect the chemical messengers (neurotransmitters) used to communicate between brain cells, ultimately leading to changes in brain chemistry and communication in brain nerve cell circuitry known to regulate mood and help relieve depression.
What is TCA on a Drug Test?
When TCA is mentioned on a drug test, it refers to a test that measures the levels of tricyclic antidepressants in a patient's blood or urine sample. The reason for testing for TCAs on a drug test may vary, but it is usually done to monitor TCA levels in patients who are taking these medications to ensure that they are receiving a safe and effective dose. In some cases, the test may also be used to identify a TCA overdose in individuals who have symptoms such as dry mouth, blurred vision, constipation, trouble urinating, drowsiness, lightheadedness, or seizures.
What Are Some Tricyclic Antidepressants?
Some of the most commonly prescribed TCAs include the following:
- Imipramine (Tofranil)
- Amitriptyline (Elavil)
- Clomipramine (Anafranil)
- Desipramine (Norpramin)
- Doxepin (Silenor)
- Nortriptyline (Pamelor)
- Protriptyline (Vivactil)
- Trimipramine (Surmontil)
Is Lexapro a Tricyclic Antidepressant?
No, Lexapro is not a tricyclic antidepressant. Lexapro is the brand name for escitalopram, a selective serotonin reuptake inhibitor (SSRI). Tricyclic antidepressants (TCAs) are a group of medicines that have a similar structure and work in a similar way but have generally been replaced by antidepressants that cause fewer side effects.
What Are TCA Drugs?
Tricyclic antidepressants or TCA is a class of older-generation drugs used to treat a variety of mood, anxiety, personality, or neurological disorders. TCA is used when other treatment options are not effective.
Similar to other antidepressants, a person taking TCA will feel an improvement in their depressive symptoms from 6 to 8 weeks after starting treatment.
Treatment with TCA however comes with common side effects such as drowsiness, blurred vision, constipation, dry mouth, a decrease in blood pressure which may lead to lightheadedness, and urine retention. Other possible side effects when taking TCA include changes in weight, excessive sweating, tremor, and sexual dysfunction.
Is Flexeril a Tricyclic Antidepressant?
Flexeril is a prescription muscle relaxer. However, its structure is similar to a class of antidepressants called tricyclic antidepressants. So no, it’s not a TCA.
Is Prozac a Tricyclic Antidepressant?
Prozac, also known as fluoxetine, is not a tricyclic antidepressant. Instead, it belongs to a different class of antidepressants called selective serotonin reuptake inhibitors (SSRIs).
What Shows up as TCA on a Drug Test?
Drug tests can detect TCAs and their metabolites in the urine, for up to ten days.

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.
