Complete Blood Count (CBC)

A complete blood count, or CBC, is a common blood test that measures the different cells in your blood, including red blood cells, white blood cells, and platelets, to help your doctor evaluate your overall health and detect a wide range of conditions.

The Aspergillus fumigatus IgG antibody test is a blood test that detects the presence of IgG antibodies against Aspergillus fumigatus, a common mold found in the environment. IgG antibodies are proteins produced by your immune system when it detects a foreign substance like this fungus. This test determines whether your body has been exposed to Aspergillus fumigatus and has mounted an immune response.

You may need this test as part of a routine checkup, or if you have symptoms such as fatigue, weakness, fever, unexplained bruising, or signs of infection, so your doctor can look for conditions like anemia, infections, or blood disorders.

Your healthcare provider may order this test if you have symptoms of an Aspergillus infection, especially if you have a weakened immune system due to conditions such as HIV/AIDS, cancer, organ transplant, or long-term steroid use. Symptoms may include fever, cough, shortness of breath, chest pain, or breathing difficulties. The test is also used to help diagnose allergic bronchopulmonary aspergillosis (ABPA), a condition where the immune system overreacts to the fungus in people with asthma or cystic fibrosis.

The test is performed by drawing a small sample of blood from a vein in your arm using a thin needle. The procedure usually takes only a few minutes, you may feel a brief sting, and your sample is then sent to a laboratory for analysis.

A healthcare professional will draw a small blood sample from a vein in your arm. The blood sample is then sent to a laboratory where it is tested for the presence of IgG antibodies against Aspergillus fumigatus. The result is reported as either 'Present' (positive) or 'Not Detected' (negative), rather than as a numerical value.

Your results show whether your blood cell counts fall within normal ranges. Abnormal levels may point to conditions such as anemia, infection, inflammation, or clotting problems, and your doctor will explain what your specific numbers mean and whether follow-up testing is needed.

A 'Present' (positive) result means that IgG antibodies against Aspergillus fumigatus were detected in your blood. This could indicate: a current Aspergillus infection, a past infection that has resolved, or an allergic response to the fungus. A 'Not Detected' (negative) result means no antibodies were found, which could indicate no exposure to the fungus, or that the infection is very early and antibodies haven't developed yet. Your healthcare provider will interpret your results in context with your symptoms, medical history, and other test results.
