Overview
There are no other diagnostic studies associated with [disease name].
OR
[Diagnostic study] may be helpful in the diagnosis of [disease name]. Findings suggestive of/diagnostic of [disease name] include [finding 1], [finding 2], and [finding 3].
OR
Other diagnostic studies for [disease name] include [diagnostic study 1], which demonstrates [finding 1], [finding 2], and [finding 3], and [diagnostic study 2], which demonstrates [finding 1], [finding 2], and [finding 3].
Other Diagnostic Studies
- Renal biopsy: Finding of acute tubular necrosis on renal biopsy may include:[1]
- Tubular dilatation and swollen tubular cells
- Loss of tubular cells or the denuded tubules
- Thinning of the tubular epithelium
- Loss of the cell brush border
- Edema of the interstitium
- Presence of cellular casts
- Novel biomarkers: Evaluation of various urinary and serum biomarkers may be helpful in patients with acute tubular necrosis to identify renal tubular injury at very early stage.
| BIomarker | Finding |
|---|---|
| Neutrophil gelatinase-associated lipocalin (NGAL) | Elevated levels are found in urine following tubular injury |
| Interleukin-18 (IL-18) | Elevated levels of IL-18 are found in urine after renal tubular injury. |
| Kidney Injury Molecule-1 (KIM-1) | Produced by proximal tubular cells after ischaemic or nephrotoxic injury. Elevated levels are found in urine following tubular injury |
| Cystatin C | Cysteine protease inhibitor filtered at the glomerulus, and reabsorbed at the proximal tubule with out secretion.Elevated levels in urine may be found after tubular insult. |
| Liver-type fatty acid binding protein (L-FABP) | Produced in proximal tubular cells and in the liver. Elevated levels are found in urine following tubular injury. |
| Tubular enzymes: Alpha glutathione S-transferase, pi-glutathione S-transferase, N-acetyl-beta-glucosaminidase | Tubular enzymes are elevated in urine following renal tubular injury |
| Retinol binding protein (RBP) | Produced by the liver and completely filtered by theglomeruli and reabsorbed, bot secreted by proximal tubular cells. It is released into urine following injury involving renal tubules. |
