Instructions
Add exactly 4 mL random urine to a myoglobin transport tube within one hour of collection. Freeze and ship frozen.
Transport tube, product #177447, is available through Client Supply.
Exactly 4 mL of urine in the myoglobin transport tube is required to achieve the required pH of >8.0. More than 4 mL of urine will lower the pH outside acceptable range.
Note: Myoglobin in urine is very unstable unless the pH is between 8.0 and 9.0.
Collect and ship specimens Monday-Thursday only.
