Comparison between analysis forms

In modern medicine, the importance of precise diagnostics and individual health analyses has greatly increased. Different body fluids and excretions, such as blood, saliva, urine, stool and respiratory gas, offer valuable insights into a person's state of health. These analyses provide comprehensive information about the body, from metabolic processes to potential diseases.

Which forms of investigation and analysis provide which opportunities?

As you can see in the following article, there are many options and variants to get important information about our body. Basically, it always depends on the question, which analysis form can provide the most input.

In this blog post, we now turn our attention to individual variants and highlight different features.

Laboratory tests of blood, saliva, stool and urine

The aim of laboratory diagnostics is to determine the causes of a disease and to use this as the basis for responsible and targeted therapy. The tests performed differ significantly in scope and applicability.  

Blood Lab

A blood lab should contain information about the functioning of internal organs and systems, that is, about the quality of the blood itself, about the supply of minerals, about the liver, gall bladder, heart, kidney, and pancreas function.

An important part of laboratory diagnostics is the examination of the supply status with regard to micronutrients, in particular:

  • Vitamins
  • Minerals
  • Amino acids
  • Trace elements
  • Antioxidants
  • Fatty acids


In particular, the examination of thyroid parameters should be in focus. Patients often have a poorly adjusted thyroid status, and there are also unrecognized inflammatory processes or autoimmune diseases of the thyroid gland. Often, quite crucial factors for the good functioning of the thyroid gland are missing.

Saliva test

A saliva test can reveal a great deal about our hormonal status. Hormones such as cortisol, progesterone, estradiol, testosterone and DHEA, can be measured in saliva and used to assess free hormones. The timing of the determination should not be done involuntarily, because hormones are subject to certain cycles that must be taken into account.


A stool examination provides valuable information regarding our immune defense, tendencies to allergies, skin diseases, inflammations, nutrient deficiencies due to insufficient breakdown in the small intestine, contamination by fungi or other pathogens. Histamine intolerance should also be mentioned in this context.

Urine test

Some metabolic diseases can be detected very easily by targeted urine diagnostics. Heavy metal contamination can also be detected in the urine after prior provocation.

Respiratory gas analysis

In addition to the possibilities of classical diagnostics of lung indications and respiratory problems, the respiratory gas analysis has the great advantage of being able to generate

Recommendations for action in the areas of nutrition and training

via the interpretation of the respiratory gases. This is one of the special features of this form of analysis!

Respiratory gas analysis is a fascinating method to determine important health parameters. With uVida Food and uVida Activity, these values are not only made accessible, but also useful. Here you can learn which values are analyzed and how they can improve your life.

  1. Breathing rate: The number of breaths per minute, also called breathing rate, is a key parameter. It tells you about your metabolism, your athletic level, and your stress level. uVida shows you how to optimize your breathing rate so your body runs more efficiently.
  2. Breathing Volume: The volume of each breath affects how efficiently your body takes in oxygen and releases carbon dioxide. With uVida Activity, you'll get recommendations for your workout so that your body is more oxygenated, which also optimizes fat metabolism.
  3. Oxygen uptake: Your body needs oxygen to produce energy. uVida Activity helps you optimize your oxygen uptake during exercise to increase your performance.
  4. CO2 output: Carbon dioxide output is another important parameter. It can give clues about your metabolism and energy production. uVida Food uses this information to adjust your diet.
  5. Respiratory Quotient: Often abbreviated as RQ, this value is an important parameter in respiratory analysis and is used to determine the type of metabolism that takes place in our bodies during a particular activity. More specifically, the respiratory quotient indicates the ratio between the carbon dioxide (CO2) produced and the oxygen (O2) consumed.


This is only an excerpt of body data, which are determined via the respiratory gas analysis. All these data are used to generate adequate recommendations for nutrition and exercise, thus ensuring individuality in the recommendations for action.

The multiple forms of analysis for blood, saliva, urine, stool and breath gas are cornerstones of precise medical diagnostics. They enable healthcare providers to gain sound insights into an individual's health status and take targeted action to prevent and treat disease. From blood analysis, which provides comprehensive information on the cardiovascular system and metabolism, to respiratory gas testing, which provides insights into lung function and metabolism, each form of analysis plays a critical role in health monitoring and optimization. Advancing technology and the continuous development of these analytical methods
promise a promising future for medical diagnostics, in prevention, and form a mainstay for early intervention and healthy living.
