Checking Frequency Data: From Numbers to Medical Claims

From Herbert Eder – an internationally sought-after frequency expert

A number with several decimal places appears precise. Yet it may still be medically ambiguous. Anyone wishing to evaluate a frequency list or a device report should therefore distinguish between three levels: the technical specification, its association with a biological process, and the claimed benefit to humans.

What was actually determined?

According to NIST guidelines, a measurement result must include a sufficiently described measured quantity, a unit, and the associated uncertainty. [1] If a frequency is specified, one would need to ask which process is repeating and how the value was obtained.

Does a number come from a measurement, a calculation, or a list provided by the manufacturer? Its origin makes a difference. A program label bearing the name of an organ or pathogen is, first and foremost, a designation. It does not, in and of itself, indicate any biological property.

Display Accuracy and Validity of the Assignment

A device might be able to generate an output frequency with a high degree of accuracy. However, this does not necessarily mean that this frequency is relevant to a specific disease. Technical accuracy addresses the question of calibration; medical classification requires other data.

Even a repeated positive result during a test run is initially just an observed signal. To use this as evidence of a pathogen, the method would have to, for example, reliably distinguish between suitable samples or individuals with and without the relevant finding. Other possible causes of the positive result would have to be investigated.

A Concrete Test of Diagnostic Claims

In 2001, Lewith and colleagues conducted a blinded study of an electrodermal allergy test. The 30 participants were divided into two groups based on previous skin tests. The method under investigation was unable to reliably distinguish between these groups for the environmental allergens studied. [2]

This finding pertains to the test in question and its specific research question. It is not a judgment on every electrical measuring device. However, it demonstrates why a clear device display cannot replace an independent diagnostic test. For a different product, its own data would need to be provided.

One treatment study answers a different question

Dailey and colleagues compared active TENS with sham TENS and a group that did not receive TENS in 301 women with fibromyalgia. After four weeks, active TENS use showed more favorable results for movement-related pain. [3] A clearly defined treatment goal was examined here.

The study therefore provides no evidence that a frequency list diagnoses or eliminates pathogens. Nor does a change in pain automatically mean that its cause has been cured. The result must be described in terms of the endpoint that was actually studied.

Four Documents That Make a Proposal Verifiable

Ask for the exact device name, a technical description of the signal, its specific intended use, and relevant studies. Check whether the cited study examines the same objective: detection, symptom relief, or altering the course of a disease.

The article on complete signal specifications explains the technical side. The Study Guide supports medical review. A long list of precisely stated numbers only becomes meaningful once their origin and their claimed significance have been verifiably documented.
