Electronic microscopy tests are also performed to determine the ultrastructure of analyzed tissue. This is a renowned centre within the specialty, receiving more than 9,000 annual studies, among which approximately 160 are fine needle taps. The area has German origin equipment to process and cut tissue, and state-of-the-art optic microscopes for digital microphotography and immunofluorescence, a useful technique for telepathology and interconsultation with other health centers.
