ENTAMOEBA HISTOLYTICA AB, IGG

LAB3132

Collect

Serum separator tube.

Specimen Preparation

Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL) Parallel testing is preferred and convalescent specimens must be received within 30 days from receipt of the acute specimens. Mark specimens plainly as "acute" or "convalescent."

Unacceptable Conditions

Contaminated, heat-inactivated, hemolyzed, or severely lipemic specimens.

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)

Notes

In the case of extraintestinal complications, a positive antibody can indicate amebiasis even though stool findings are negative.

Performed

Tue, Fri

Methodology

Semi-Quantitative Enzyme-Linked Immunosorbent Assay

Reported

1-5 days

Synonyms

  • Amebiasis histolytica Antibody
  • E. histolytica Antibody
  • LAB3132
  • AMB

Ordering Recommendations

Aid in the detection of amebic liver abscess. Test is not useful for intestinal infection.

Reference Interval

Effective February 6, 2017

8 U or less: Negative - No significant level of detectable E. histolytica IgG antibody.
9 - 11 U: Equivocal - Repeat testing in 10-14 days may be helpful.
12 U or greater: Positive - IgG antibody to E. histolytica detected, suggestive of a current or past infection.

Interpretive Data

Seroconversion between acute and convalescent sera is considered strong evidence of recent infection.  The best evidence for infection is a significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time.
