Turnaround times

The times do not include transport of specimen to the laboratory or the administrative process to print and post/email reports. Service users must allow for transport and reporting time when ordering tests.
Clinical background:
Vitamin C is a negative acute phase reactant. Request will only be accepted if CRP checked and is not elevated. Deficiency (which is rare in western societies) can lead to fatigue and easy bruising. Structurally weakened tissue, as in scurvy, is swollen, tender and bleeding.
Large doses of Vitamin C are generally regarded as non-toxic. GI symptoms, vitamin B12 deficiency, increased iron absorption and increased oxalate production may occur.
