IV. The impact of the detection threshold on the results

The detection threshold of a saliva test is the minimum concentration of a substance that must be present for the test to detect it. It is crucial to understand that the detection threshold can directly influence the accuracy and reliability of the results.

1. Tests at 15 ng/ml:


  • Increased sensitivity: These tests are able to detect lower concentrations of substances, making them particularly useful in situations where early detection is essential.
  • Use by Law Enforcement: As mentioned previously, law enforcement favors 15 ng/ml tests due to their increased sensitivity. This means that an individual could test negative during a roadside check with a 50 ng/ml test, but positive with a 15 ng/ml test.
  • Detection over a longer period: Tests at 15 ng/ml can detect substances several days after consumption, which can be crucial for certain applications, such as employment checks or sports tests.


2. Tests at 50 ng/ml:


  • Less sensitive: These tests require a higher concentration of the substance to give a positive result. This can result in false negatives, especially if the substance was consumed several days before the test.
  • Cost: Often, 50 ng/ml tests can be cheaper, but at the expense of sensitivity and accuracy.
  • Applications: These tests may be appropriate for situations where early detection is not essential, or where cost is a major concern.


3. Importance of choosing the right threshold:


  • Context of use: The choice between a 15 ng/ml test and a 50 ng/ml test should depend on the context of use. For example, for a traffic stop or employment test, a more sensitive test might be preferable.
  • Understand the implications: Users should be aware of the implications of the results. A negative result with a 50 ng/ml test does not guarantee that a 15 ng/ml test will give the same result.

In summary, the detection threshold is a key element to consider when choosing a saliva test. Understanding the pros and cons of each threshold is essential to making an informed choice based on specific needs.

V. How to choose the right test?

The decision to opt for a 15 ng/ml or 50 ng/ml saliva test should not be taken lightly. Here are some elements to consider to make the right choice:
