If you need to know which are the vitamin D reference ranges or you require more information about vitamin D in a blood test, you can visit normal vitamin D in a blood test.
A high level of vitamin D in the blood is not common but may occur due to excessive intake of vitamin D or high exposure to sunlight. However, it is often a result of long-term use of vitamin D supplements./p>
The vitamin D blood test usually measures only 25-hydroxy vitamin D [25(OH)D], which is the main circulating form of vitamin D.
Vitamin D [25(OH)D] blood values are usually given in ng/ml but sometimes you can see these values in nmol/l following the International System of Units (SI). In case your values are in nmol/l you can convert them using this tool:
A high vitamin D [25(OH)D] level in the blood means:
The vitamin D level in the blood is slightly elevated. Vitamin D is produced through sunlight exposure, so levels can be higher in certain groups, such as surfers or lifeguards.
It is advisable to monitor these levels in future blood tests and consult your doctor if you are taking vitamin supplements./p>
The vitamin D level in the blood is very high, and it is necessary to reduce it to avoid serious health problems./p>
A severe increase in vitamin D may cause symptoms such as nausea, anorexia, weakness, and constipation.
Values over 150 ng/ml are considered toxic and may lead to hypercalcemia (high calcium concentration in the blood), hypercalciuria (excessive calcium excretion in urine), and suppression of parathyroid hormone (PTH), along with their related complications.
A vitamin D [25(OH)D] level in the blood higher than normal may be a sign of the following diseases:
A vitamin D [25(OH)D] level in the blood higher than normal may be a sign of the following diseases:
Most cases of excessive vitamin D concentration in the blood are related to inappropriate use (such as unlicensed or poorly formulated supplements) or abuse of vitamin D supplements. If this is the case, you should stop taking vitamin D supplements, and if your doctor considers it necessary, reduce your dietary calcium intake.

The following values are considered to be above the normal range:
IMPORTANT: These levels are expressed in ng/ml. They are an example of a healthy adult of about 45 years old with no known disease with an adequate sunlight exposure and not taking any medication. The ranges can be different depending on the laboratory or on your personal circumstances.
