  Diagnosing lupus is difficult because signs and symptoms vary considerably from person to person. Signs and symptoms of lupus may change over time and overlap with those of many other disorders. […] No one test can diagnose lupus. The combination of blood and urine tests, signs and symptoms, and physical examination findings leads to the diagnosis. […] Blood and urine tests may include: […] A positive test for the presence of these antibodies produced by your immune system indicates a stimulated immune system. While most people with lupus have a positive antinuclear antibody (ANA) test, most people with a positive ANA do not have lupus. […] Lupus can harm your kidneys in many different ways, and treatments can vary, depending on the type of damage that occurs. In some cases, it’s necessary to test a small sample of kidney tissue to determine what the best treatment might be. […] Skin biopsy is sometimes performed to confirm a diagnosis of lupus affecting the skin. […] Because the symptoms of lupus can mimic so many other health problems, you may need patience while waiting for a diagnosis. Your doctor must rule out a number of other illnesses before diagnosing lupus.

  Systemic lupus erythematosus (SLE), commonly known as lupus, is an autoimmune illness that affects many organs and systems in the body. Lupus is a chronic condition, but symptoms tend to cycle in alternate periods of „flares” (or „flares-ups”) and remissions. There is no known cure, but numerous treatments are available. […] A diagnosis of lupus is generally based on laboratory tests that exclude other diseases that may have similar symptoms, and specific serologic tests blood tests that determine the presence of certain antibodies. […] Patients with lupus characteristically have the following lab test results: Antibodies against their own cells. Almost all people with lupus test positive for antinuclear antibodies (ANA). […] About one-third of patients with systemic lupus erythematosus (but not those with cutaneous, drug-induced, or neonatal lupus) develop kidney disease, known as lupus nephritis.

[…] Kidney involvement is common in systemic lupus erythematosus (SLE). An abnormal urinalysis with or without an elevated plasma creatinine concentration is present in a large proportion of patients at the time of diagnosis of lupus nephritis (LN). […] The diagnosis of LN is ideally confirmed by a kidney biopsy. A kidney biopsy is important to define the nature of kidney involvement, exclude other causes of kidney injury, and determine the histopathologic subtype of LN. Biopsies are also important to assess disease activity and chronicity. […] The presence of lupus nephritis (LN) should be suspected in patients with known systemic lupus erythematosus (SLE) who develop an active urinary sediment with persistent hematuria and/or cellular casts, proteinuria, and/or an elevated serum creatinine.

However, some histopathologic features are highly characteristic of LN. […] A kidney biopsy should be performed in most patients with SLE who have clinical or laboratory evidence of kidney involvement to establish the correct diagnosis and determine the histologic subtype of LN. […] The revised ISN/RPS classification system divides glomerular disorders associated with SLE into six different patterns (or classes) based upon kidney biopsy histopathology.
