A folic acid test may be done to: Check for the cause of anemia. A folic acid test is often done at the same time as a test for vitamin B12 levels because a lack of either vitamin may cause anemia. Check for malnutrition or problems absorbing (malabsorption) folic acid. See if treatment for folic acid deficiency or vitamin B12 deficiency is working. See if a woman has enough folic acid to prevent certain birth defects and allow her baby to grow normally.
You may need to keep getting these shots, take high doses of a supplement, or get it nasally after that. If you don't eat animal products, you have options. You can change your diet to include vitamin B12-fortified grains, a supplement or B12 injections, or a high-dose oral vitamin B12 if you are deficient.
Your doctor may recommend: Shots of vitamin B12 (monthly or more often, if needed) Vitamin B12 supplements, in pill form or as a nasal spray Treatment of underlying conditions, such as Crohn's disease, celiac disease, or alcoholism Dietary changes
The only way to treat celiac disease is to permanently remove gluten from your diet. This allows the intestinal villi to heal and to begin absorbing nutrients properly. Your doctor will teach you how to avoid gluten while following a nutritious and healthy diet. They will also give you instructions on how to read food and product labels so you can identify any ingredients that contain gluten.
Symptoms can improve within days of removing gluten from the diet. However, you shouldn't stop eating gluten until a diagnosis is made. Removing gluten prematurely may interfere with test results and lead to an inaccurate diagnosis.
Test Method 1 : Most of the time, blood is taken from a vein on the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
