Serological diagnosis of Indian visceral leishmaniasis: direct agglutination test versus rK39 strip test

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2006
We evaluated the direct agglutination test (DAT), using freeze-dried (FD) and aqueous (AQ) antigen, and the rK39 immunochromatographic strip test in the diagnosis of Indian visceral leishmaniasis (VL). Sera from 508 subjects (150 parasitologically confirmed patients with VL, 100 and 153 healthy controls drawn from non-endemic and endemic regions ...

Evaluation of a direct agglutination latex particle test for human chorionic gonadotropin

American Journal of Obstetrics and Gynecology, 1969
Abstract A direct agglutination latex particle slide test for HCG has been evaluated. This test uses latex particles coated with anti-HCG as the only reagent. It is convenient to use and requires only 2 minutes to perform. In our series it had an accuracy rate (about 98 per cent) comparable to the presently available pregnancy tests. This test may be

The direct agglutination test: a non specific test specific for the diagnosis of visceral leishmaniasis

Annals of Tropical Medicine And Parasitology, 1997
Serology has an important role to play in the diagnosis of the severe clinical syndrome of visceral leishmaniasis (VL). The direct agglutination test (DAT), a simple agglutination test which requires no laboratory facilities, has become the preferred test, particularly for field studies.

Evaluation of a new direct latex agglutination tube test (UCG-Macrotube) for pregnancy

American Journal of Obstetrics and Gynecology, 1978
A new direct latex agglutination tube test for pregnancy the UCG-Macrotube was compared with the UCG-LYPHO test and the UCG-SLIDE test. 328 urine specimens were evaluated by each test and results were compared with a quantitative gonadotropin assay performed at an independent laboratory. All 3 tests were negative in 136 cases and all were positive in

Direct agglutination test (DAT): improvement of biosafety for laboratory diagnosis of visceral leishmaniasis

Transactions of the Royal Society of Tropical Medicine and Hygiene, 2011
In this study, the direct agglutination test (DAT), using 2-mercaptoethanol (2-ME), kaolin or N-acetylcysteine (NAC) as sample diluents, was used to assay 89 samples from visceral leishmaniasis (VL) patients and 130 samples from patients with other diseases and healthy individuals. Maintaining a cut-off of 1:100, the DAT assays with 2-ME, kaolin or NAC

The latex agglutination test: standardization and comparison with direct agglutination and dot ELISA in the diagnosis of visceral leishmaniasis in India

Annals of Tropical Medicine And Parasitology, 1998
Laboratory diagnosis of visceral leishmaniasis (VL) is usually based on the detection of Leishmania amastigotes in samples of bone marrow or splenic aspirate obtained by invasive procedures. Serological tests serve as a useful adjunct and are especially valuable in early or highly immune cases where amastigotes may be too scanty to be seen easily.

Rapid detection of Leishmania infantum infection in dogs: a comparative study using fast agglutination screening test (FAST) and direct agglutination test (DAT) in Iran

Parasitology Research, 2009
Canine visceral leishmaniasis (CVL) is not only a veterinary problem but has also a serious public health importance. Rapid detection of CVL is highly important for control of human visceral leishmaniasis in Iran. This study was aimed to compare the fast agglutination screening test (FAST) with direct agglutination test (DAT) as a standard serological ...

Direct agglutination test for early diagnosis of Indian visceral leishmaniasis.

The Journal of the Association of Physicians of India, 1997
In a prospective study, 80 cases of fever with hepatosplenomegaly, anemia and leucopaenia coming from the hyperendemic zones for visceral leishmaniasis of North-Bihar, India were screened and subjected to bone marrow or splenic puncture for demonstration of Leishman-donovan bodies (LDB) and DIRECT AGGLUTINATION TEST (DAT) with antigen prepared by ...

Operational validation of the direct agglutination test for diagnosis of visceral leishmaniasis.

The American journal of tropical medicine and hygiene, 1999
The validity of the direct agglutination test (DAT) for visceral leishmaniasis (VL) was studied with a standardized field kit on 148 clinically suspected persons and 176 healthy controls recruited between 1993 and 1994 from an endemic area in Gedaref State, Sudan.
