Why undergoing this examination?

Omega-3 fatty acids belong to the polyunsaturated group. These types of fatty acids intervene in the correct functioning of different physiological processes and are considered essential; however, our organism is not always in optimal conditions to synthesize them. For this reason, they should be obtained through diet or food supplements. A low omega-3 index in the body is associated with an increased risk of a cardiovascular or cerebrovascular event. On the other hand, it has been shown that there is an association between increased consumption of these fatty acids and a lower predisposition to diseases such as depression or attention deficit/hyperactivity disorder (ADHD). Its consumption is also fundamental during pregnancy and lactation, for the correct neuronal development of the baby.

What is this exam?

This test evaluates the presence in the body of two of the main omega-3 fatty acids: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) obtained both through diet and through the synthesis in the body of alpha-linolenic acid (ALA). Later, a calculation is made of the percentage of EPA and DHA in relation to the total fatty acids present in the red blood cell membrane.

For whom is it indicated?

Suitable for all those people who wish to proactively control their health, as well as in the following situations:
• Patients with cardiovascular diseases.
• Patients with chronic diseases, including asthma, metabolic, immune or inflammatory changes.
• Patients with low mood or depression.
• Children with suspected Attention Deficit/Hyperactivity Disorder (ADHD).
• During gestation, in order to ensure the correct nutritional content to the baby.
