Collection Info |
1. A minimum of 2 mg of liver tissue is required for analysis. This is typically a piece of tissue from a 14-gauge needle biopsy at least 0.5 cm long. If an 18-gauge needle is used, the tissue must be at least 1 cm in length. The 18-gauge needle produces a specimen that is thin and fragile and difficult to remove from paraffin. 2. Send in Mayo metal-free specimen vial (blue label) supplied by Mayo Medical Laboratories. 3. Any specimen vial other than a Mayo metal-free vial used should be plastic, leached with 10% nitric acid for 2 days, rinsed with redistilled water, and dried in clean air. 4. Send specimen refrigerated (keep specimen cool with frozen coolant April-October, refrigerated coolant November-March). 5. Paraffin block is also acceptable. NOTE: 1. Include suspected diagnosis and clinical information. 2. AGE IS REQUIRED ON REQUEST FORM TO CALCULATE IRON INDEX. |
