Although controversial, high dose intravenous vitamin C (ascorbic acid) has been used to effectively treat various conditions. These include various viral infections and cancer. A protocol for use of high dose vitamin C may be obtained by writing, The Riordan Clinic, 3100 N. Hillside, Wichita, KS 67219.

Specimen type, preparation and processing is the same as for plasma vitamin C. Additional information required on the requisition is the grams of vitamin C given (15 grams, 25 grams, 50 grams, etc). Draw specimen from vein on opposite arm used for IVC.

Note: Diabetic patients or health care workers caring for diabetic patients who monitor their blood glucose with a finger stick strip and meter please note that high level post I.V.C. (ascorbic acid) will cause a FALSE POSITIVE on the finger stick test. Wait eight hours or more to check the patient's glucose with the finger stick and meter. If a test is needed during this time, have a serum glucose performed in a certified clinical (reference) laboratory.

Doctors who wish to order kits, please call our lab directly to set up an account before ordering. 316-684-7784
