Humoral Immunity Evaluation Panel
Reference Values:
HUMORAL IMMUNITY EVALUATION
DIPHTHERIA ANTITOXOID, ELISA
REFERENCE RANGE: > or =0.01 IU/mL (Post-Vaccination)
INTERPRETIVE CRITERIA:
or =0.01 IU/mL Protective Antibody Level
A minimal four-fold increase between pre-immune and post-immunization sera is considered a normal
response to diphtheria toxoid.
This test was developed and its performance characteristics have been determined by Focus Diagnostics.
Performance characteristics refer to the analytical performance of the test.
HAEMOPHILUS INFLUENZAE B VACCINE RESPONSE, ELISA
REFERENCE RANGE: > or =1 ug/mL post-vaccination (protective level)
INTERPRETIVE CRITERIA:
or =1.0 ug/mL Protective Antibody Level
IgG antibody to polyribosylribitol phosphate (PRP), the capsule polysaccharide of Haemophilus
influenzae type b, is measured in micrograms/mL (ug/mL), based on correlations with a reference Farr
radioimmunoprecipitation assay (RIA). The exact level of antibody needed for protection from infection
has not been clarified; values ranging from 0.15 ug/mL to 1.0 ug/mL have been reported. A four-fold
increase in the PRP IgG antibody level between pre-vaccination and post-vaccination sera is considered
evidence of effective immunization.
TETANUS ANTITOXOID, ELISA
REFERENCE RANGE: > or =0.50 IU/mL (Post-Vaccination)
INTERPRETIVE CRITERIA:
or =0.50 IU/mL Protective Antibody Level
A minimal four-fold increase between pre-immunization and post-immunization sera is considered a
normal response to tetanus toxoid. Levels greater than or equal to 0.50 IU/mL are generally considered
protective, whereas levels less than 0.05 IU/mL indicate a lack of protective antibody. Levels between
0.05 and 0.49 IU/mL are indeterminate for the presence of protective antibody and may indicate a need
for further immunization to tetanus toxoid.
