Ordering Recommendations

Evaluate the ability of a patient to produce antibody to pure protein vaccine after vaccination to rule out antibody deficiency.

Reference Interval

Antibody concentration of > 0.1 IU/mL is usually considered protective.

Interpretive Data

Responder status is determined according to the ratio of a one-month post-vaccination specimen to pre-vaccination concentration of tetanus IgG antibodies as follows:

1.  If the post-vaccination concentration is less than 1.0 IU, the patient is considered a nonresponder.
2.  If the post-vaccination concentration is greater than or equal to 1.0 IU, a patient with a ratio of less than 1.5 is a nonresponder, a ratio of 1.5 to less than 3.0, a weak responder, and a ratio of 3.0 or greater, a good responder.
3.  If the pre-vaccination concentration is greater than 1.0, it may be difficult to assess the response based on a ratio alone.  A post-vaccination concentration above 2.5 IU in this case is usually adequate.

Interpretive Data

If this specimen had been tested prior to 05/20/2014, the result may have been 10% less than this value due to a different testing method.
In most patients, serum concentrations of 10–20 μg/mL effectively suppress chronic asthmatic and other bronchospastic symptoms. Serum concentrations of 5–10 μg/mL reportedly control apneic spells in neonates without causing apparent side effects. Peak concentrations above 20 μg/mL are often associated with toxicity.  For effective treatment, some patients may require serum levels outside this range. Therefore, the expected range is provided only as a general guide, and individual patient results should be interpreted in light of other clinical signs and symptoms.

Optimize therapy for thiopurine drugs. Identify thiopurine metabolite concentrations that may lead to toxicity.

Reference Interval

Components
Reference Interval
6-TG Nucleotides RBC230-400 pmol/8 x 108 RBC
6-MMP Nucleotides RBCLess than 5701 pmol/8 x 108 RBC

Interpretive Data

Concentrations of 6-thioguanine nucleotide (6-TGN) less than 230 pmol/8 x 108 RBC may indicate a reduced response to therapy; 6-TGN concentrations greater than 400 pmol/8 x 108 RBC may indicate a higher risk for leukopenia. Concentrations of 6-methyl mercaptopurine nucleotide (6-MMPN) greater than 5700 pmol/8 x 108 RBC may indicate a higher risk for hepatotoxicity.
