TCA Drug Test Strips – Tricyclic Antidepressants TCA/1000

TCA Drug Test Strips – Tricyclic Antidepressants TCA/1000

These TCA drug test strips are single-panel urine dip strips that screen a urine specimen for Tricyclic Antidepressants at a 1000 ng/mL cutoff. Each test gives a preliminary result in minutes and is sold individually, so you can order exactly the quantity your program needs.

Tricyclic antidepressants (TCAs) are prescription medications that are screened as a class. A TCA strip screens for this class separately from standard drug panels.

This product is Forensic Use Only. Related options are listed in our single-panel drug test strips category, including the TCA/1000 dip card.

TCA Dip Strip Cutoff Level

This dip strip screens for one target. Programs that need several drugs at once should compare our multi-panel cups and dip cards.

TCA Drug Test Strips Features

Each dip strip is individually sealed and includes an internal control line, so every test shows whether it was run correctly.

The dip strip is used with urine collected in a separate cup. That keeps the cost per test low and lets you add a TCA screen to an existing collection process.

Because it screens only one target, the dip strip can be paired with a multi-panel cup or dip card when TCA needs to be added to a broader drug screen.

How to Use and Read Results

Always follow the package insert supplied with the exact lot, because collection steps and reading times can differ between devices.

1. Collect the urine specimen in a clean, separate collection cup.
2. Remove the strip from the sealed pouch and hold it by the top end.
3. Dip the arrow end into the urine without passing the MAX line, for the time stated in the insert.
4. Lay the strip flat on a clean, non-absorbent surface and read the result within the stated window.

• Negative: both the control line (C) and the test line (T) appear for the test. A faint test line is interpreted according to the insert.
• Non-negative (preliminary positive): the control line appears but the test line does not. This is a preliminary screening result, not a confirmed result.
• Invalid: no control line appears. Do not interpret the result; repeat the test with a new device.

A non-negative screen should be followed by laboratory confirmation according to your program’s procedure before any final decision is made. A screening result does not show impairment, dose or the time of use.
