Mycophenolic Acid1.0 - 3.5 µg/mLGreater than 25.0 µg/mL
Mycophenolic Acid Glucuronide35.0-100.0 µg/mLNot well established
Mycophenolic Acid acyl-glucuronideNot well establishedNot well established

Interpretive Data

The therapeutic range is based on serum pre-dose (trough) draw at steady-state concentration. A proposed therapeutic range is 1.0-3.5 µg/mL for a 2 g/day dose. A 3 g/day dose may have plasma concentrations up to 5.0 µg/mL. Trough concentrations between 2.0 and 4.0 µg/mL have been suggested to maximize efficacy and minimize adverse effects. Mycophenolic acid glucuronide is an inactive metabolite and a range of 35.0-100.0 µg/mL indicates normal metabolism. During the first two weeks of transplantation, mycophenolic acid glucuronide concentrations are typically 100 - 250 µg/mL.  Mycophenolic acid acyl-glucuronide is an active metabolite and the therapeutic and toxic ranges are not well established. Adverse effects of toxicity include abdominal pain, peripheral edema, cardiac abnormalities, hypertension and electrolyte disturbances.

Reference Interval

< 0.10 U/L: Negative
0.10-0.32 U/L: Equivocal
> 0.32 U/L: Positive

Interpretive Data

Over 50 percent of healthy adults have a relatively high background of specific M. pneumoniae IgG antibodies in their sera, probably because of past M. pneumoniae infections. Therefore, paired sera obtained with a time interval of 1 to 3 weeks are highly recommended in adults to confirm reinfection by M. pneumoniae, which is demonstrated by a significant change in IgG antibodies. A significant change is indicated if one specimen is above 0.32 U/L and the other is below 0.20 U/L.

Additional Technical Information

Ordering Recommendations

Stand-alone test for autoimmune neuropathies. Test by itself is not diagnostic and should be used in conjunction with other clinical parameters to confirm disease.

Reference Interval

Less than 1000 TU

Interpretive Data

An elevated IgM antibody concentration greater than 999 TU against myelin-associated glycoprotein (MAG) suggests active demyelination in peripheral neuropathy. A normal concentration (less than 999 TU) generally rules out an anti-MAG antibody-associated peripheral neuropathy.
