Does lupus cause hypoxia?
When the heart fails to keep up, the rest of the body suffers by receiving less and less oxygen (a condition called hypoxia). Pulmonary hypertension occurs in about 10% of people with lupus. On rare occasions pulmonary hypertension responds to corticosteroids and immunosuppressive treatment.
What tests are done for hypoxia?
In general, hypoxia and/or hypoxemia is diagnosed by physical examination and by using oxygen monitors (pulse oximeters), determining, the oxygen level in a blood gas sample and may include pulmonary function tests.
What tests are indicative of lupus?
Blood and urine tests may include:
- Complete blood count. This test measures the number of red blood cells, white blood cells and platelets as well as the amount of hemoglobin, a protein in red blood cells.
- Erythrocyte sedimentation rate.
- Kidney and liver assessment.
- Antinuclear antibody (ANA) test.
How are test results analyzed for lupus?
98% of all people with systemic lupus have a positive ANA test, making it the most sensitive diagnostic test for confirming diagnosis of the disease. The test for anti-nuclear antibodies is called the immunofluorescent antinuclear antibody test. In this test, a blood sample is drawn and sent to a laboratory.
What is silent hypoxia?

Why does lupus cause low WBC?
A lower than normal lymphocyte count is found on the full blood count in about 95% of lupus patients. This is due to the presence of antibodies to lymphocytes which results in the destruction of the antibody-coated lymphocytes.
How are lab tests used to diagnose lupus?
There are several important things to keep in mind with lab tests: Lab work alone usually cannot diagnose lupus. When a positive antinuclear antibody (ANA) test is accompanied by several other clues that doctors look for in diagnosing lupus, it is often a strong indication to consider lupus.
Can a positive lupus test be a negative?
Test results that suggest lupus can be due to other illnesses or can even be seen in healthy people. A test result may be positive one time and negative another time. Different laboratories may produce different test results.
What to do if your ANA test is positive for lupus?
