Overview

The Phosphatidylserine Antibody IgG test measures IgG antibodies against phosphatidylserine, a phospholipid present on cell membranes. It is useful in the diagnosis, management and possible prevention of thrombotic complications as part of antiphospholipid syndrome. It also supports evaluation of autoimmune diseases such as lupus, rheumatoid arthritis and Sjogren's syndrome.

Doctor's Notes

Reviewed by — MBBS, MD (General Medicine) · Reg. No. 8052

"As an allergy/immunology specialist, I use this test to evaluate patients with suspected antiphospholipid syndrome, especially when there is a history of unexplained thrombosis or pregnancy loss. Laboratory results alone are not diagnostic and must be interpreted together with clinical history and additional tests."

Understanding Your Results

Results of the Phosphatidylserine Antibody IgG test should be interpreted in the context of the patient's clinical condition and other laboratory tests. A single antibody result is not sufficient to establish or exclude antiphospholipid syndrome.
📊

Negative

IgG antibodies to phosphatidylserine were not detected. It does not completely exclude antiphospholipid syndrome if clinical suspicion remains.

📊

Equivocal / Borderline

Uncertain result. Repeat testing may be considered based on clinical scenario.

📊

Positive

IgG antibodies to phosphatidylserine were detected. Result should be correlated with clinical features and additional antiphospholipid antibody testing.

⚠️ When to Consult a Doctor:

Consult a doctor if you have unexplained blood clots, recurrent pregnancy loss, or features of autoimmune disease such as fatigue, joint pain, skin rash, or persistent fever. This test should be ordered and interpreted by a clinician.

Limitations

  • ⚠Antibody levels can vary over time
  • ⚠A single positive result is not diagnostic by itself
  • ⚠Testing may be negative in some cases of antiphospholipid syndrome
  • ⚠Different laboratories may report different reference ranges
  • ⚠Clinical correlation and repeat testing are often required

Risks & Considerations

  • ●Mild pain or bruising at the needle site
  • ●Excessive bleeding is rare
  • ●Local infection is rare
  • ●Dizziness or fainting during blood collection

Interfering Factors

  • ●Haemolysed, lipaemic or icteric samples
  • ●Sample not stored refrigerated or frozen within recommended time
  • ●Using wrong tube such as EDTA or heparin plasma instead of serum
  • ●Repeated freezing and thawing of serum

Frequently Asked Questions

What is the Phosphatidylserine Antibody IgG test?
It is a blood test that measures IgG antibodies against phosphatidylserine, a phospholipid found on cell membranes. It is used in the evaluation of antiphospholipid syndrome and is also included in the workup of certain autoimmune diseases.
Who should get this test?
It may be advised for people with unexplained blood clots, recurrent pregnancy loss, or symptoms suggesting an autoimmune disease such as lupus, rheumatoid arthritis or Sjogren's syndrome. A doctor decides whether this test is appropriate.
What type of sample is collected?

A positive result indicates that IgG antibodies to phosphatidylserine were detected. It does not diagnose antiphospholipid syndrome by itself. It should be interpreted with clinical features and additional investigations.
What does a negative result mean?
A negative result means IgG antibodies to phosphatidylserine were not detected in the sample. It can help support clinical assessment but does not completely exclude antiphospholipid syndrome if clinical suspicion remains.
