Reference Interval

Effective 05/20/2014:

Before 05/20/2014:

15.0-40.0 ug/mL

Interpretive Data

Most patients achieve a satisfactory therapeutic response in the serum concentration range of 10–40 μg/mL, while concentrations above 60 μg/mL can be associated with toxicity.  Some patients may require serum levels outside this range. Therefore, the expected range is provided only as a general guide, and individual patient results should be interpreted in light of other clinical signs and symptoms

PHOSPHATIDYLSERINE AB IGG/M/A

LAB1180

 

Collect

Serum separator tube.

Specimen Preparation

Transfer 0.5 mL serum to an ARUP Standard Transport Tube. (Min: 0.25 mL)

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)

Performed

Sun, Tue, Wed, Fri, Sat

Methodology

Semi-Quantitative Enzyme-Linked Immunosorbent Assay

Reported

1-3 days

Synonyms

  • LAB1180
  • PHOS AB
  • PHOSPHATAB

Ordering Recommendations

Not a recommended panel for the diagnosis of antiphospholipid syndrome (APS). The combined IgG and IgM Phosphatidylserine test is the preferred second-line testing in seronegative APS.

Reference Interval

Components
Reference Interval
Phosphatidylserine Antibody IgGLess than 11 U/mL
Phosphatidylserine Antibody IgMLess than  25 U/mL
Phosphatidylserine Antibody IgALess than  20 U/mL


Interpretive Data

IgG and/or IgM antibodies to phosphatidylserine (aPS) may be associated with a positive test for anti-cardiolipin autoantibodies (aCL) and risk for obstetric antiphospholipid syndrome (APS). Strong clinical correlation is recommended in the absence of lupus anticoagulant, IgG and/or IgM cardiolipin and/or beta2 glycoprotein antibodies.

Isolated presence of IgM or IgG antibodies to aPS may have questionable clinical significance for APS and/or SLE.

If results are positive, repeat testing with two or more specimens drawn at least 12 weeks apart to demonstrate persistence of antibodies.

Results should not be used alone for diagnosis and must be interpreted in light of APS-specific clinical manifestations and/or other criteria phospholipid antibody tests.
