Rationale 1: An elevated LE prep supports the diagnosis of SLE, as there are normally no LE cells present.
Rationale 2: Hematuria is often present in patients with SLE.
Rationale 3: The normal result of this test is negative. The presence of anti-SM antibodies supports the diagnosis of SLE.
Rationale 4: The C3 normal range for females is 76–120 mg/dL. SLE reduces these levels.
