Vitamin C Test

$49

This Vitamin C Test measures the amount of vitamin C in the blood. Vitamin C is essential in the building and repairing of bones and as well as the healing of wounds. Vitamin C is absorbed through food only, so it’s important to maintain a proper diet with fruits and vegetables. Those with vitamin C deficiencies may be prone to anemia, weakened bones/teeth, nosebleeds, and inflamed joints. Priority Lab Testing’s convenient and reliable Vitamin C Test is recommended for those experiencing such symptoms.

Testing Method:
Blood draw
Test Preparation:
Overnight fasting is required (i.e. no eating or drinking anything besides water for 8 hours prior to testing). Patients should refrain from eating fruits or taking vitamin C supplements 24 hours prior to collection.

How Our Vitamin C Test Works

Do you need to test your vitamin C levels? Luckily, getting your test is easy. Just click “add to cart” and check out with your Vitamin C test. Then, plan ahead. You’ll need to fast overnight before your test to ensure that you have accurate levels. You may also need to avoid eating fruits or taking any vitamin C supplements at least 24 hours before your test. Once you’re ready, you can just come in to one of our 4,000+ convenient testing locations. There’s no need to make an appointment; our technicians will take care of you when you come in. 

You’ll come in, have your blood drawn by one of our qualified technicians, and have your test sent off to our qualified lab. Once your test has been taken, your part is done! Most of the time, patients are on their way within 30 minutes. You’ll receive your results within a few days.

When Do You Need a Vitamin C Test?

You may need a vitamin C test for a number of reasons. Most notably, you may find that you need a vitamin C test if you’re noticing bone or joint weakness, including more frequent injury. You may also need a vitamin C test if you have noticed more overall joint pain or inflammation, or if you have been struggling to deal with regular nosebleeds. 

Interpreting Your Results

When you receive your results, you should have no trouble determining what they mean. In the “reference range” column, you’ll see the normal range of vitamin C levels for adults. You’ll then see a “results” range that will lay out your specific results, and a “flag” range that will define whether your results fall within normal levels. If you have very low vitamin C levels, you may need to consult a doctor to determine your next steps. Our care counselors can also help you more effectively evaluate the results of your vitamin C test.

Comprehensive Vitamin Panel vs. Vitamin C Panel

Sometimes, you may wonder if you need to do a vitamin C panel or take a comprehensive vitamin panel test. A comprehensive vitamin panel can provide you with insights into all of your vitamin levels, letting you get a deeper look at whether you may have any nutritional deficits. A vitamin C panel, on the other hand, will provide information about your vitamin C levels alone. Consider whether you have specific symptoms of vitamin C deficiency or if you are interested in identifying potential symptoms of overall health deficits and other problems before determining which panel is right for your needs.

FAQs

  • The vitamin C test is highly accurate. However, if you do not fast before your appointment, or if you have taken vitamin C supplements in the day before the test, you may find that your results do not accurately reflect your actual vitamin C levels. 

  • Our care counselors can help you better interpret and understand the results of your vitamin C test. They can also provide you with contact information for a physician if you have problems that may require additional treatment.

  • Vitamin C is primarily absorbed through foods. If you have low vitamin C levels, it could be a sign of a diet that does not contain adequate fruits and vegetables. A doctor can provide you with more insight about how to address a potential vitamin C deficiency.
