Colostrum should be given in a stress-free environment because stress reduces antibody absorption, he said.
The Venereal Disease Research Laboratory test result was positive (titer [greater than or equal to]640), and a fluorescent treponemal antibody absorption test result was strongly reactive.
And it is important that the colostrum is fed as soon as possible after the calf is born, he added, because the antibody absorption level rapidly deteriorates.
Laboratory tests revealed that his erythrocyte sedimentation rate (ESR), antinuclear antibody (ANA) level, rheumatoid factor (RF) value, and fluorescent treponemal antibody absorption (FTA-ABS) titers were within normal limits.
More sensitive nontreponemal tests such as the rapid plasma reagin (RPR) and the Venereal Disease Research Laboratory (VDRL) are used for initial screening, while specific treponemal tests such as the fluorescent treponemal antibody absorption (FTA-ABS) are used to confirm the diagnosis.
The 2 commonly used specific treponemal tests are Treponema pallidum hemagglutination (TPHA) and fluorescent treponemal antibody absorption (FTA-ABS).

In terms of antibody absorption, the red cells in the sample have been bathed in patient plasma while in vivo, and, in general, additional in vitro time spent in association with red cells will not materially affect the concentration of antibodies in the serum.
Lumbar puncture was performed and cerebrospinal fluid analysis revealed that his glucose level (62 mg/dl), protein level (35 mg/dl), and cell count were normal and that his fluorescent treponemal antibody absorption (FTA-ABS) and Venereal Disease Research Laboratory (VDRL) assays were nonreactive.
