Anti-Cardiolipin IgG

High levels of Anti-Cardiolipin IgG in your blood could indicate that your body's immune system is mistakenly attacking its own cells, a characteristic of autoimmune diseases like lupus. This particular antibody targets cardiolipin, a lipid molecule found in the inner mitochondrial membrane of cells. Elevated levels could also suggest an increased risk of blood clots, as these antibodies can interfere with the normal clotting process. Certain medications, such as phenytoin (used to treat seizures) and penicillin, can also cause an increase in Anti-Cardiolipin IgG levels. Additionally, infections like syphilis or HIV can trigger a temporary rise in these antibodies. Therefore, a high Anti-Cardiolipin IgG level could be a sign of an autoimmune condition, a side effect of specific medications, or a response to certain infections.

Symptoms of high levels of Anti-Cardiolipin IgG may include unexplained bleeding or bruising, recurrent miscarriages in women, skin discoloration (livedo reticularis), neurological symptoms like migraines or seizures, and in severe cases, symptoms related to blood clots such as swelling, pain, and redness in the affected area.

Low levels of the Anti-Cardiolipin IgG biomarker in your blood could suggest that your body isn't producing as many antibodies against its own cells, which is generally a good thing. This means your immune system is not mistakenly attacking your own body, reducing the likelihood of autoimmune diseases like lupus. However, it's important to note that certain medications, such as blood thinners, can also lower Anti-Cardiolipin IgG levels. Additionally, low levels could also mean that your body is not producing enough antibodies in general, which could potentially make you more susceptible to infections. This test is a useful tool in understanding your body's immune response and potential risks.

Symptoms of low levels of Anti-Cardiolipin IgG may not be noticeable, as this condition often doesn't cause any specific symptoms. However, if the low levels are due to a general lack of antibodies, you might find yourself getting sick more often than usual.
