From the Research
A DHA lab refers to a laboratory test that measures the levels of docosahexaenoic acid (DHA) in the blood, which is essential for brain development and function, particularly in infants and young children, as supported by the most recent study 1.
Importance of DHA Laboratory Test
The test is commonly used to assess nutritional status, especially in pregnant women, nursing mothers, and infants, as adequate DHA levels are crucial for fetal and infant brain and eye development.
- The test typically requires a blood sample, which can be collected through a standard blood draw or sometimes via a finger prick.
- Results usually indicate whether DHA levels are within normal range, deficient, or excessive.
- If levels are low, dietary changes or supplements containing DHA (typically 200-300mg daily for adults) may be recommended, as suggested by 2.
Sources of DHA
DHA is naturally found in fatty fish like salmon and mackerel, as well as in algae-based supplements for those who don't consume fish.
- Regular monitoring of DHA levels can be important for individuals with specific health concerns or dietary restrictions that might limit natural DHA intake, as highlighted by 3.
Health Benefits of DHA
The health benefits of DHA are numerous, including the prevention of cardiovascular disease, cancer, and neurological disorders, as discussed in 4 and 5.
- DHA has also been shown to have a positive effect on diseases such as hypertension, arthritis, atherosclerosis, depression, adult-onset diabetes mellitus, myocardial infarction, thrombosis, and some cancers, as mentioned in 4.
