Overview
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
OR
[Test] is usually normal for patients with [disease name].
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
OR
There are no diagnostic laboratory findings associated with [disease name].
Laboratory Findings
- Laboratory findings consistent with the diagnosis of post-streptococcal glomerulonephritis include:
- Diagnosis of preceding streptococcal infection can be determined by measuring following antibodies:[1]
- The antistreptolysin (ASO) positive
- Antinicotinamide adenine dinucleotides (anti-NAD) positive
- Antihyaluronidase (AHase), and anti–DNAse B positive
- CBC with differntial count:[2]
- Leukocytosis with neutrohilia
- CRP is raised
- Renal function tests:
- Increased levels of blood urea nitrogen (BUN)
- Serum creatinine levels are increased
- Serologic testing:[3][4]
- Hypocomplementemia such as low serum level of C3, C4, and C5.
- Urinalysis:[5]
- Proteinuria
- Hematuria
- Urine sediments show red blood cells, red blood cell casts, white blood cells, granular casts
- Dysmorphic red blood cells are characteristics findings of glomerular hematuria usually detected by performing phase-contrast microscopy
