Understanding Your Results

Results from Electron Microscopy (TEM) are interpreted by pathologists to identify ultrastructural abnormalities indicative of specific diseases.
Abnormal cellular organelles may suggest metabolic disorders
Presence of inclusions or deposits can indicate storage diseases
Changes in cell membrane or nuclear structure may point to cancer or genetic conditions
⚠️ When to Consult a Doctor:

Consult your doctor if you experience symptoms such as unexplained weight loss, persistent pain, neurological issues, or signs of infection, as these may require TEM testing for diagnosis.
