What Is a Vitamin A Retinol Test?
The Vitamin A Retinol test is a blood test that measures the amount of retinol — the main form of vitamin A — circulating in your blood. Doctors order it to check whether your vitamin A levels are too low, too high, or within a healthy range. Also called the Serum Retinol test or Vitamin A Serum test, it is performed on a venous blood sample drawn from your arm.
What Does a Vitamin A Retinol Test Measure?
This test measures a single key parameter. Here is what it tells you:
| Parameter | What It Represents |
|---|---|
| Serum Retinol | The concentration of vitamin A (retinol) in your blood, reflecting your body's current vitamin A status |
Vitamin A is essential for healthy vision, skin, immune function, bone development, and reproduction. The body cannot produce it on its own, so it must come from food or supplements.
Why Is a Vitamin A Retinol Test Done?
A doctor may order a Serum Retinol test for several reasons, from investigating symptoms to monitoring known conditions.
Common Symptoms That May Require This Test
These are the symptoms most likely to prompt a doctor to request this test:
- Night blindness or difficulty seeing in low light
- Dry, irritated, or red eyes
- Dry, flaky, or scaly skin
- Frequent infections or slow recovery from illness
- Poor wound healing
- Delayed growth in children
- General vision problems
Conditions This Test Can Help Detect
The Vitamin A Retinol test can help identify a range of conditions, including:
- Vitamin A deficiency (causing night blindness and increased infection risk)
- Vitamin A toxicity (hypervitaminosis A), resulting from excess supplementation
- Intestinal malabsorption of fats, which reduces the absorption of fat-soluble vitamins
- Cystic fibrosis and pancreatic insufficiency
- Chronic liver disease
- Coeliac disease
- Crohn's disease
- Chronic pancreatitis
Vitamin A Retinol Test for Chronic Disease Monitoring
For people living with conditions that impair fat absorption — such as coeliac disease, Crohn's disease, or cystic fibrosis — regular monitoring of vitamin A levels is an important part of ongoing care. The Cystic Fibrosis Foundation, for example, recommends screening for fat-soluble vitamin deficiencies at diagnosis and then annually. This test helps clinicians track whether supplementation is working or needs to be adjusted.
How to Prepare and What to Expect
Preparing correctly for your Vitamin A Retinol test helps ensure your results are as accurate as possible.
Do You Need to Fast?
Yes, fasting for 12 hours before the test is recommended. Eating raises vitamin A levels temporarily, which can skew results. Drinking plain water during the fasting period is fine.
Practical Tips Before Your Test
Here are a few straightforward steps to take before your appointment:
- Avoid alcohol for at least 24 hours before sample collection.
- If possible, stop taking vitamin A supplements two days before the test, as supplements can remain detectable in the blood for up to 32 hours after ingestion.
- Inform your doctor or the collection team about all medications and supplements you are taking.
- Keep yourself well hydrated with water throughout the fasting period.
- Wear a short-sleeved or loose-sleeved top for easy access to your arm.
Step-by-Step Procedure
The sample collection process is quick and straightforward. Here is what to expect:
- A phlebotomist (blood collection specialist) will ask you to sit comfortably and expose the inside of your elbow or the back of your hand.
- The area is cleaned with an antiseptic wipe.
- An elastic band is placed around your upper arm to make the veins easier to locate.
- A small needle is gently inserted into a vein to draw a blood sample.
- The blood is collected into a specialised tube, and the needle is removed; a small dressing is applied.
- The sample is processed promptly and dispatched to the laboratory for analysis.
Factors That Can Affect Accuracy
A few factors can influence the reliability of your test results:
- Not fasting before the test (eating raises retinol levels temporarily)
- Excessive light exposure or contact with certain plastics during sample handling, which can lower measured values
- Active inflammation or infection, which reduces the protein that carries retinol in the blood
- Haemolysis (breakdown of red blood cells) during or after collection
- Recent use of vitamin A supplements without prior disclosure
Understanding Your Vitamin A Retinol Test Results
Your results should always be reviewed with a qualified doctor who can consider your full health history. The table below shows general reference ranges for serum retinol.
| Parameter | Low | Normal | High |
|---|---|---|---|
| Serum Retinol | Below 20 mcg/dL | 20 to 60 mcg/dL | Above 60 mcg/dL |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can alter how your results should be read.
- Inflammation or active infection lowers the protein that transports retinol in the blood, which can make vitamin A levels appear lower than they actually are.
- Impaired kidneys retain the retinol-binding protein, which may cause retinol readings to appear moderately elevated.
- Women taking oral contraceptives may show slightly higher retinol levels due to the oestrogen content of these medications.
- During the later stages of pregnancy (beyond 20 weeks), retinol levels may appear lower, particularly when inflammatory markers are elevated.
How to Maintain Healthy Levels
These general tips support healthy vitamin A status as part of a balanced lifestyle:
- Include natural food sources of vitamin A in your diet — such as eggs, dairy, liver (in moderation), dark leafy greens, and orange and yellow vegetables like carrots and sweet potatoes.
- Choose plant-based sources of beta-carotene where possible, as the body converts it to retinol only as needed, reducing the risk of excess.
- Avoid taking vitamin A supplements without guidance from a doctor, as excess intake can be harmful.

Yes, 12 hours of fasting is recommended before the Serum Retinol test. You should also avoid alcohol for 24 hours beforehand. Drinking water during this time is perfectly fine.
This test is useful for anyone experiencing symptoms like night blindness, dry eyes, or frequent infections. It is also recommended for people with conditions that impair fat absorption, such as cystic fibrosis, coeliac disease, Crohn's disease, or chronic liver disease, as these conditions increase the risk of vitamin A deficiency.
Yes. Excess vitamin A, usually caused by over-supplementation rather than diet alone, is toxic and can cause headaches, nausea, bone pain, and liver damage. Your doctor can advise on safe intake levels based on your results.
It is advisable to stop vitamin A supplements two days before the test, as supplements can remain detectable in the blood for up to 32 hours after ingestion. Always inform your doctor or the collection team about all supplements and medications you are currently taking.
Yes, the Vitamin A Retinol test can be done at any age. It is particularly relevant for children showing signs of delayed growth, frequent infections, or vision problems, as these can be early indicators of vitamin A deficiency.
