Test info

  
Synaptophysin by IHC
  
12376 - Technical only, 12379 - Technical & interpretation
  
LAB12376
LAB12379
  
  • All IHC stains will include a positive control tissue
  
  • Use in a panel for neuroendocrine tumors
  • Other neuroendocrine markers include chromogranin, Leu-7 (and NSE)
  • Synaptophysin is more specific than NSE and has not been detected in non-neuroendocrine cells
  • Synaptophysin is usually used in combination with chromogranin to increase the sensitivity
