The concept of indication , originating in Latin indicated, refers to act and consequence of indicating (that is, to indicate something by means of signs and signs). The word also refers to the signal It serves as a brand or leads to focus on a certain thing. For example: "I did not understand the indication of the agent and I ended up losing myself", "The coach gave an indication to the striker to play next to the line", "With a slight indication, the chief ordered that the suspect be confined".

For the medicine , an indication represents a valid reason to perform a certain medical procedure or surgery, provide a medication or use a test . Typically, these indications are regulated and authorized by professional associations or state agencies. The opposite of the indication is the contraindication (a condition that increases the risks when using a medication or drug).

In this case, we can also underline that there are two types of contraindication. Thus, in the first place, there is the absolute call that is called this way because it establishes the firm prohibition of the use of a treatment in what is globally.

And secondly is the one known as relative contraindication that receives its name from the fact that it is determined and positioned against the use of a treatment determined by the circumstance of what is produced is an increase in the relationship between risk and risk. benefit.

The so-called protected geographical indication (generally identified by the acronym PGI ), on the other hand, is the denomination of a product which has a specific origin and whose value or quality are associated with that site of origin. Usually, this indication is based on what the region or locality is called. The most common example of an PGI is roquefort , the cheese produced in the French region of Roquefort-sur-Soulzon and that is often used to name all blue cheeses.

It is known as indication traffic signs to the notices that inform drivers about certain issues of interest. These signs have a blue background and present the elements in white.

When talking about them, it must be established that there is a broad typology of them, which has resulted in a clear classification of them:

Signs of general indications, as would be the case of those indicating the principle of a highway or highway.

Service signals What they do is notify and inform the driver that services such as repair shops or relief stations are available on that road.

Lane signs, which have as a clear function the proper account of information regarding them. Thus, among these are those of lanes that are reserved for certain vehicles based on the speed that they can or should reach them.

Orientation signs Within this category, another classification is established that divides them into confirmation, pre-analysis, road identification, address, location…
