I haven’t shared the knowledge of poison testing for some time, and the last time I shared the knowledge of hair testing, the comments on the article made me feel a little nervous.
To that end, I would say: there are many things in life that you can’t control, and if you can accept this, then it will help you better accept everything life throws at you, including the things you don’t like. Be honest about what you do. You have to accept the fact that you can’t change the past, but you can create the future.
Let’s get back to business. Drug urine test strip is actually a common name, and it is often called drug urine test board, drug urine test board, etc. In fact, its product name is drug detection kit (colloidal gold method), which has an irreplaceable role in drug control, and has the advantages of small cost, simple operation and short use process.
Here’s a flowchart of how to use drug test strips:
Tear open the test strip bag
The packaging bag of the drug test strip is made of aluminum foil, which is vacuum packed, and in addition to the test strip, there is a disposable dropper and a small bag of desiccant. After tearing the bag, you can use your mobile phone or watch as a timer, and the timer is set to a 5-minute countdown.
Remove the test strip
After removing the urine plate, lay it flat on a tabletop. The test plate must not be placed in an inclined place or held in the hand, it must be placed flat or the accuracy of the results will be affected.
Use a pen to mark the number of the person tested on the urine test plate. For example, if the person tested is Zhang San, write Zhang San on the urine test board.
Aspirate urine with a disposable dropper.
Urine is dripped into a round hole at one end of the test plate, which is a urine hole. The rectangle in the middle is the hole for observation and cannot be dripped into urine. 3 drops of urine are enough, more or less drops will cause the water pressure into the urine test plate to be high or low, which will affect the accuracy of the results.
At the same time, turn on the countdown of the timer to start the countdown.
Wait for the result
Wait patiently for the results, do not move the urine plate.
Observe the results
With a countdown of 0, observe the results in a rectangular hole in the middle of the urine plate.
The urine sample should be fresh urine, i.e. the person should be tested as soon as possible after urinating.
After the drug test strip is removed from the bag, it should be used within 1 hour, after 1 hour, the test strip will get wet and cause the test result to be wrong.
Observe the results at 5 minutes, do not observe the results after 10 minutes. According to the test strip reaction stability test, the stable level is reached at 5 minutes, and after 10 minutes, due to the humidification of the surface of the test strip film, the color rendering effect will change, which will affect the correct interpretation.
Finally, I would like to say this: you have to learn how to recognize automated thoughts that don’t help you in the face of setbacks and adversity. Once you’re able to identify them, you’ll be able to remind yourself to adopt a more beneficial way of thinking and accept yourself.
