It shows results even after the effects wear off. Therefore, it gives patients a good idea about the likelihood of passing a professionally administered test.

Urine tests are known to be affordable, but there is a drawback. Compared to professional screening, at-home urine screens are less accurate. It provides a pass or fails reading at a specific threshold—a substance with a lower concentration found in the urine results to pass.

Furthermore, urine screens also give occasional false-positive results. Some food groups, OTC medications, vitamins, and prescription trigger a positive test result. So when you get a positive test result, consider taking another testing panel.

If you have a positive urine screen with an OTC drug test, the use of a hair screen is advisable. Considering it is the best choice to detect the odds of passing or failing a professional screen. Just prepare enough funds before you buy it.

Parental Drug Testing

One of the most common at home drug tests is parental drug testing. It is applicable for parents who suspect their children to use illicit substances.

Taking this type of drug test has a lot of considerations. Parents need to know the importance of conversations with their children. Learn how to start a discussion about drug abuse. Find the appropriate timing of drug testing for children. Identify which method is the best to use. Most important of all, how to do it sensitively.

Parental drug testing primarily concerns the long-term physical and mental health of a child. The risk of drug dependence starts for children who are under the age of 18. The worst part is that it extends into adulthood.

There are symptoms that a child exhibits when using an illicit substance. Certain drugs make a child feel excessive fatigue, unusual moodiness, and problems at school. Any presence of these behaviors warrants a parent to do drug testing for their kids. Do this without invading the child’s privacy.

Resorting to parental drug testing requires extra precaution. Why? Because this option is sensitive. It might lead to several family issues and later damage their relationship. Also, provide the most effective type of test to use and consider the time frame.

An important reminder: false-positive results are inevitable. It will not be reliable if parents choose a hair screen too soon after drug use. A urine test is not accurate if done too long after substance consumption.

Drug tests at home help prevent further substance abuse. Do it right by using a specific type of screening for some reason or substance. Always consider the drug used and the time frame. Be careful when picking a home drug testing product.
