Test Includes

Hepatitis C Virus (HCV) Antibody Cascade to Quantitative PCR and Genotyping; Hepatitis B Surface Antigen (HBsAg) Screen, Qualitative; Hepatitis B Surface Antibody, Quantitative: Hepatitis B Core Antibody with Reflex; QuantiFERON®-TB Gold Plus


Special Instructions

For HCV Antibody Cascade (PCR/Geno) [144127]: Submit two samples, preferably one refrigerated unopened gel-barrier tube and one frozen serum/plasma pour off tube.

If reflex test is performed, additional charges/CPT code(s) may apply.

One or more of these tests may exhibit interference when a sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to collection of a sample.


Specimen Requirements


Specimen

Serum and/or plasma and whole blood


Volume

Two 10 mL gel-barrier tubes (preferred), one serum transfer tube (4.5 mL), and 1 mL x four tubes in QuantiFERON-TB Gold Plus kit


Minimum Volume

Two 10 mL gel-barrier tubes (preferred), one serum transfer tube (4.5 mL), and 1 mL x four tubes in QuantiFERON-TB Gold Plus kit


Container

Two 10 mLgel-barrier tubes and one serum transfer tube and QuantiFERON-TB Gold Plus kit.


Collection

QuantiFERON-TB Gold Plus kit: Blood collection tubes should be at room temperature at the time of collection. Refer to collection instructions included with draw kit. Special specimen collection kit contains four gel-barrier tubes as noted above. All four tubes are required for a single test result. Each tube is designed to draw only 1 mL and fill time may be longer than other blood collection tubes. Because of the limited vacuum in these tubes, use a needle and holder (not a butterfly) to collect QuantiFERON® specimens. If a butterfly is required, first collect other required tubes or use another Vacutainer® tube to purge the butterfly line of air and then proceed with drawing the QuantiFERON® tubes. Fill tubes to the black fill line on the tube. If tubes are underfilled or overfilled (see kit insert), immediately collect a replacement tube.

Following proper fill, label the tubes appropriately and shake tubes 10 times firmly enough to ensure the entire surface of the tube is coated with blood cells to solubilize the antigen on the tube walls. After shaking, the volume may fall below the fill line. Do not centrifuge or refrigerate specimens.

Return each of the four properly filled, labeled, and shaken tubes to the box labeled "QFT kit." Seal the top by removing tape from the adhesive. To preserve cellular viability, specimens should be collected and sent the same day, at room temperature, so as to arrive at the lab as soon as possible and within 14 hours of collection.


Storage Instructions

Refrigerate 1 gel-barrier tube; maintain 1 gel-barrier tube at room temperature; freeze 4.5 mL serum transfer tube; maintain QuantiFERON-TB Gold Plus kit at room temperature (must be incubated witin 16 hours of collection).


Causes for Rejection

QuantiFERON-TB Gold Plus kit: Expired collection tubes. Four-tube QuantiFERON collection kit: Specimen centrifuged, refrigerated, or frozen; specimen more than 14 hours old on receipt by lab; receipt of three tube collection kit.


Test Details


Use

Biologic therapies can be used to treat many different autoimmune diseases, such as Inflammatory Bowel Disease, Rheumatoid Arthritis, and Psoriasis. Biologic therapies can be life-changing drugs but they can also suppress the immune system and put the patient at risk of infection. Because of this risk, it is recommended by the American Academy of Dermatology (AAD), American College of Gastroenterology (ACG) and the American College of Rheumatology (ACR) to screen patients for certain infectious diseases, including hepatitis B, hepatitis C and tuberculosis.1-3


Limitations

Patients who are negative for HBsAg may still have acute type B viral hepatitis. There is sometimes a "core window" stage when HBsAg has become negative and the patient has not yet developed the antibody (anti-HBs). On such occasions, both tests for anti-HBc are usually positive and anti-HBc, IgM is the only specific marker for the diagnosis of acute infection with hepatitis B. In cases with strong clinical suspicion of viral hepatitis, serologic testing should not be limited to detecting HBsAg, but should include a battery of tests to evaluate different stages of acute and convalescent hepatitis.

Presence of anti-HBs is not an absolute indicator of resolved hepatitis infection nor of protection from future infection. Since there are different serologic subtypes of hepatitis B virus, it is possible (and has been reported) for a patient to have antibody to one surface antigen type and to be acutely infected with a virus of a different subtype. Thus, a patient may have coexisting HBsAg and anti-HBs. Transfused individuals or hemophiliacs receiving plasma components may give false-positive tests for antibody to hepatitis B surface antigen.

A negative QFT-Plus result does not preclude the possibility of M. tuberculosis infection or tuberculosis disease: false negative results can be due to stage of infection, co-morbid conditions that affect immune function, incorrect handling of the blood collection tubes following venipuncture, incorrect performance of the assay, or other individual immunological variables. Heterophile antibodies on non-specific interferon-gamma production from other inflammatory conditions may mask specific responses to CD4+ and CD*+ T cell antigens. A positive QFT-Plus result should not be the sole or definitive basis for determining infection with M. tuberculosis. Incorrect performance of the assay may cause false-positive results. A positive QFT-Plus result should be followed by further medical evaluation for active tuberculosis disease.
