This test is a medical evaluation that helps your healthcare provider gather important information about your health. The results can be used to diagnose a condition, monitor an ongoing problem, or guide decisions about your treatment and follow-up care.

The Adenine test measures the amount of adenine, a nucleobase, in your blood serum. Adenine is one of the four main nucleobases that make up DNA and RNA (along with guanine, cytosine, and thymine/uracil). While adenine is naturally produced by your body and is essential for genetic material, abnormal levels may indicate certain metabolic disorders.

Your provider may recommend this test if you have symptoms that need clarification, risk factors for certain conditions, a family history of disease, or an existing health condition that requires regular monitoring to make sure your treatment plan is working as expected.

Your healthcare provider may order this test if they suspect a rare metabolic disorder affecting how your body processes purines (the category of molecules that adenine belongs to). This may include conditions like adenine phosphoribosyltransferase deficiency or other purine metabolism disorders. Symptoms that might prompt testing include kidney stones, recurrent urinary tract infections, or unusual neurological symptoms.

The test is usually performed in a clinic, hospital, or laboratory setting by a trained healthcare professional. Depending on the type of test, it may involve providing a small sample or having a simple examination. The procedure is generally quick, and most patients tolerate it well.

A healthcare professional will draw a small sample of blood from a vein in your arm. The blood is collected in a special tube, allowed to clot, and then the serum (the liquid part of blood) is separated for analysis. The procedure is quick and similar to routine blood tests.

Reference range

Specimen: serum

No specific fasting required. Maintain usual fluid intake unless otherwise instructed. Avoid dietary supplements containing adenine or purine-rich foods 24 hours prior to collection if possible.

Frequently asked questions

Do I need to fast before this test?
Follow your healthcare provider's instructions. Some tests may require fasting, while others do not. Check with your doctor or the testing lab beforehand.
Are there any risks with this blood test?
The risks are minimal and similar to routine blood draws, including slight bruising, soreness, or rarely, infection at the puncture site.
How long does it take to get results?
Results times vary depending on the laboratory. Specialized metabolic tests may take longer than routine blood work. Your healthcare provider can give you a better timeline.
What do abnormal results mean?
Abnormal adenine levels may indicate a metabolic disorder, but results must be interpreted by your healthcare provider in context. Additional testing may be needed to confirm a diagnosis.
