People having TCA treatment have higher suicidal tendency. So if you have an employee who is on TCAs, then you have to take special precautions for him or her. You should not put them in a place that brings a lot of stress. You should not make any statements or remarks that depress them as this would precipitate the depression. Sometimes leaving them in isolation would bring in them the thoughts of committing suicide. So you must put them in places where there is lot of activity. All this can be done only if you know that they are on tricyclic antidepressants which the person would never say in most of the cases. But you can use the drug stick tricyclic test to assess this.
One of the most common forms of suicide among depressed patients is the drug over dosage of TCAs. But sometimes, it can also be homicidal. In either case, if you are a policeman, then you can use drug immunoassay tricyclics for detecting the presence of TCA in urine of the deceased. You can do this as a preliminary test before sending the body to the forensic examination where the results may sometimes be manipulated. In such cases you can show the result of your drug imipramine screening as a proof of your argument.
Promazine is another TCA which is also abused frequently. In these entire drug screening procedures the methodology is simple. In drug promazine testing you just have to dip the test strip in the urine sample for 10 seconds and then leave it undisturbed for 5 minutes and check the color lines. If the test lines appear along with control line, then the test is considered negative whereas if only the control line appears, it is considered positive.
