SOLUBLE LIVER ANTIGEN IGG ANTIBODY

LAB3458

Collect

Serum separator tube.

Specimen Preparation

Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.3 mL)

Unacceptable Conditions

Contaminated, heat-inactivated, hemolyzed, or 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)

Performed

Sun, Tue, Thu

Methodology

Semi-Quantitative Enzyme-Linked Immunosorbent Assay

Reported

1-4 days

Synonyms

  • ANTI-SOLUBLE LIVER ANTIGEN
  • ANTI-SLA
  • LAB3458
  • SOLUBLE LIVE

Additional Technical Information

Ordering Recommendations

Recommended for the evaluation of autoimmune liver disease or hepatitis of unknown etiology.

Reference Interval

0.0-20.0 U: Negative
20.1-24.9 U: Equivocal
Greater than or equal to 25.0 U: Positive

Interpretive Data

The presence of SLA antibodies has almost 100% specificity for autoimmune hepatitis, although only 12-30% have these antibodies.  Thus, a negative SLA IgG test does not rule out autoimmune hepatitis.

SOLUBLE TRANSFERRIN RECEPTOR

LAB3178

Collect

Serum separator tube or plasma separator tube. Also acceptable: green (sodium or lithium heparin), lavender (EDTA), or pink (K2EDTA).

Specimen Preparation

Transfer 1 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.3 mL)

Unacceptable Conditions

Contaminated, severely hemolyzed, icteric, or lipemic specimens.

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

After separation from cells: Ambient: 72 hours; Refrigerated: 1 week; Frozen: 1 month (avoid repeated freeze/thaw cycles)

Performed

Sun-Sat

Methodology

Quantitative Immunoturbidimetry

Reported

Within 24 hours

Synonyms

  • Transferrin Receptor Level
  • LAB3178
  • STR

Reference Interval

Male - 18 years & older: 2.2-5.0 mg/L
Female - 18 years & older: 1.9-4.4 mg/L

Interpretive Data

People of African descent and those residing at 5,200 feet (1,600 meters) above sea level were found to have a 6% higher normal value.  These differences were additive.  Reference intervals have not been established for pregnant females, patients under 18 years of age, and recent or frequent blood donors.

Serum soluble transferrin receptor increases in iron deficiency and is usually unaffected by chronic disease states.  In general, to increase sensitivity and specificity, the measurement of serum soluble transferrin receptor should be performed in combination with other tests of iron status, including ferritin, TIBC, and serum iron (refer to table below).
