The results of the assay were compared with RPR and TPHA
CIs: Confidence intervals EIA: Enzyme immunoassay ELISA: Enzyme-linked immunosorbent assay FTA-abs: Fluorescent treponemal antibody absorption test IgG: Immunoglobulin G IRB: Institutional Review Board NPV: Negative predictive value NAAT: Nucleic acid amplification techniques PCR: Polymerase chain reaction PPV: Positive predictive value RPR: Rapid plasma reagin rDNA: Recombinant DNA STARD: Standards for Reporting Diagnostic Accuracy Studies STD: Sexually transmitted disease TPHA
At this threshold two samples out of 53 were WB indeterminate with single TpN17 reactivity, yet they were TPHA
Under the umbrella of TPHA
we could put together a strategy and then go out and raise money, do talks, get articles in daily newspapers etc., and spread awareness all over the world and do amazing work in the field with scientists who actually generally understand the sustainable use of wildlife.
Following the testing of the 437 serum samples, the results of the CIA were compared to those of the TPHA
if EIA is used for screening, EIA if TPHA
is used for screening); IgG-immunoblot for T.
Em caso de positividade, recomenda-se a confirmacao diagnostica com teste treponemico por aglutinacao de particulas (TPHA
) ou teste fluorescente por absorcao de anticorpos (FTAAbs), entretanto a ausencia desses nao deve retardar o tratamento.
As of August, there were nearly 1,100 TPHA
members, Levy said.
PCL triol ([M.sub.n] ~ 900 g/mol), methyl [alpha]-D-glucopyranoside (Me[alpha]DGlu, [greater than or equal to]99%), 2-(hydroxymethyl)phenyl-[beta]-D-glucopyranoside (salicin, p-toluenesullonic acid (p-TsOH, [greater than or equal to]98.5%), Amberlyst-15 (Amb15), terephthalalcle-hyde (TPhA
, 99%), [alpha]-bromoisobutyryl bromide (BriBuBr, 98%), triethylamine (TEA, >99%), anhydrous tetrahydro-furane (THF, 99.9%), 4,4'-dinonyl-2,2'-dipyriclyl (dNdpy, 97%), and copper (II) chloride (Cu[Cl.sub.2] >99%) were purchased from Sigma-Aldrich and used without purification.
test detects antibodies against a specific treponemal antigen.
(1) if the enzyme immunoassay is positive, these experts suggest confirmation with another treponemal test, usually TPPA or TPHA
. Then a nontreponemal test can be used to stage the infection.
EKG, electrocardiogram; FBC, full blood count; TPHA
, treponema pallidum hemagglutination assays; VDRL, venereal disease research laboratory test.
Laboratory tests, including routine biochemical tests, were within normal limits; hepatitis A, B, C, HIV, syphilis (VDRL, TPHA
), vasculitic (ANA, RF, anticardiolipin antibodies, ENA profile) markers were negative; B12 and folic acid levels were normal.
