Intended Use

This test detects the presence of antibodies against Hepatitis E Virus

Clinical Significance

After an incubation period ranging from 15 to 60 days, HEV-infected patients develop symptoms of hepatitis with appearance of anti-HEV IgM antibody in serum, followed by detectable anti-HEV IgG within a few days. Anti-HEV IgM may remain detectable up to 6

Methodology

ELFA

Reference Range

Non Reactive

Interpretation

Collection Instruction

Observe universal precautions when collecting a blood specimen. Record the time of day when the blood test is drawn. Follow the recommended order of draw when collecting blood in tubes. To obtain valid results, do not fasten the tourniquet for longer than 1 minute. Release and remove the tourniquet as soon as possible after the blood begins to flow. Prolonged tourniquet application can cause stasis and hemoconcentration. Wrap the tourniquet around the arm 3 to 4 inches (7.5 to 10.0 cm) above the venepuncture site. If a blood pressure cuff is used in place of a tourniquet, inflate it to no more than 40mm Hg. The veins become more prominent and easier to enter when the patient forms fist. However, there must not be vigorous hand exercise (pumping) - vigorous hand pumping can cause changes in the concentration of certain analytes in the blood. The preferred venepuncture site is the antecubital fossa. Mix additive tubes by inversion. Do not shake the blood specimen. Hemolysis may result from vigorous shaking and can invalidate test results. Use gentle inversions. Collect the blood specimen from the arm without an intravenous (IV) device, if possible. IV infusion can influence test results. Do not use the arm bearing a dialysis arteriovenous fistula for venepuncture unless the physician specifically authorizes it. Because of the risk of cellulitis, do not take specimens from the side on which a mastectomy or axillary lymph node dissection was performed.
