However, other inflammatory conditions, such as lupus, can have a positive anti-NT5C1A. [1] As of 2019, it remains to be established whether a positive anti-NT5C1A antibody test can make muscle biopsy unneeded. [1] Inclusion body myositis MRI. Muscle imaging can help establish the pattern of muscle involvement and selection of a biopsy site. [1]
The skin weighs an average of 4 kg (8.8 lb), covers an area of about 2 m 2 (22 sq ft), and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue.
