Antiphospholipid Antibody (APLA) Panel

The Lupus Anticoagulant (LAC) Profile is a group of blood tests that help measure how lupus anticoagulant antibodies affect blood clotting. These tests include: 

1. Dilute Russell viper venom time (DRVVT) – Screen:

Measures clotting time. Prolonged clotting time suggests the presence of lupus anticoagulant.

2. Activated Partial Thromboplastin Time (APTT):

Assesses the intrinsic clotting pathway. If prolonged, it may indicate inhibitors like lupus anticoagulant.

3. Lupus Anticoagulant Test:

Confirms the presence of lupus anticoagulants (antibodies that target phospholipids and interfere with normal clotting mechanisms).

The Beta 2 Glycoprotein 1 IgG Serum test detects the presence of immunoglobulin G (IgG) antibodies against Beta 2 Glycoprotein 1, a protein that plays a crucial role in regulating blood clotting. IgG indicates a chronic or ongoing immune response against β2GPI, which is often associated with an increased risk of blood clotting disorders such as those seen in APS. Elevated levels of these antibodies suggest a higher risk for thrombotic events, such as deep vein thrombosis (DVT), stroke, or miscarriage, particularly when coupled with other clinical factors. By detecting IgG antibodies, this test aids in diagnosing APS and determining the need for medical interventions to manage clotting risk, including anticoagulant therapy or closer monitoring in pregnancy.

The Anti Cardiolipin IgG Antibody test detects specific immunoglobulins IgG antibodies, against cardiolipin, a phospholipid found in cell membranes. These antibodies can indicate autoimmune disorders such as antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE).

IgG antibodies are typically produced by the immune system later in an immune response and remain in the body for a longer time period, suggesting a more chronic or ongoing immune system activation. Therefore, the anticardiolipin IgG test is often used to diagnose chronic conditions or long-term immune responses, such as persistent blood clot formation in disorders like antiphospholipid syndrome (APS).

The Anti Cardiolipin IgM Antibody test detects specific immunoglobulins IgM antibodies against cardiolipin, a phospholipid found in cell membranes. These antibodies can indicate autoimmune disorders such as antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE).

IgM antibodies are typically the first antibodies produced by the immune system in response to an infection or antigen, and the presence of IgM antibodies in the blood sample may suggest recent or acute immune system activation. Thus, the Anti Cardiolipin IgM Antibody test is often used to diagnose acute conditions or recent immune responses, such as recent blood clot formation in disorders like antiphospholipid syndrome (APS).

The Beta 2 Glycoprotein 1 IgM, Serum test checks for the presence of immunoglobulin M (IgM) antibodies against Beta 2 Glycoprotein 1, a protein that helps regulate blood clotting. IgM antibodies are usually the first type of antibody the body makes in response to new infections or autoimmune issues. Elevated IgM (Immunoglobulin M) levels can indicate an ongoing or recent infection, or they can suggest an autoimmune response. In the context of pregnancy, high IgM levels might be associated with certain conditions like antiphospholipid syndrome or other immune-related issues that could affect pregnancy outcomes. When doctors notice high IgM levels, particularly in pregnant women, it can guide decisions like monitoring the pregnancy more closely for signs of complications, including preterm labor or fetal growth restrictions, considering blood thinners (like heparin or aspirin), especially if the patient is at risk of clotting disorders, which are associated with higher IgM levels in some cases and  checking for infections (e.g., TORCH infections) that could pose risks to the baby.
