agglutination reagent tests to screen for infectious
diseases :

- Syphilis

- VDRL
- TPHA
- Infectious
Mononucleosis (I.M)
- Toxoplasmosis
|
Hepatitis
B– Direct Latex reagent test : |
Test
to detect HBsAg. |
|
Qualitative
test.
The
test is based on the latex agglutination reaction.
Latex particles coated with rabbit gamma-globulins
are highly reactive to hepatitis B surface antigen
(HBsAg).
In the event of a positive reaction (agglutination),
various agglutination patterns are obtained. If the
test is negative (no HBsAg), no agglutination occurs.
The kit is intended for professional use. |
Syphilis
RPR Carbon– Direct Latex reagent test
: |
Test
for the slide determination of reagins. |
|
In
patients infected by Treponema pallidum, the test
detects the presence of certain antibodies known as
plasma reagins. The reaction of RPR Carbon Antigen
with those reagins generates information on the presence
and extent of the infection.
RPR Carbon Antigen is a non-treponemal preparation,
derived from the Venereal Disease Research Laboratory
(VDRL) antigen. The preparation contains finely divided
carbon particles in order to enhance agglutination
and facilitate reading.
Test is for professional use. |
Syphilis
VDRL antigen– flocculation
test : |
|
|
Subjects
infected with T
pallidum
generally produce reagins, a group of antibodies directed
against tissue components of these infected patients.
In the presence of the VDRL reagent (association of
antigen and lipids), reagins induce a visible agglutination.
This
test is intended for professional use. |
Syphilis
TPHA– Hemaglutination test
: |
Syphilis
is a veneral disease caused by T. pallidum. |
|
Infected
subjects produce specific anti-T. pallidum antibodies
that can be detected in the serum using avian red
blood cells pre-coated with an antigenic extract of
the microorganism. Passive hemagglutination is one
of the methods of choice for the detection of anti-T.
Pallidum antibodies.
The TPHA test is based on the detection of specific
anti-T. Pallidum antibodies by the passive agglutination
method. In the presence of anti-T. Pallidum antibodies,
coated avian red blood cells agglutinate forming a
smooth mat at the bottom of the microtiter plate wells.
If the result is negative result, a well-defined pellet
is observed.
The
test is intended for professional use. |
I.M
– Infectious mononucleosis Hemaglutination
slide test
: |
Qualitative
or semi-quantitative method. |
|
Mononucleosis
is an infectious disease induced by the Epstein-Barr
virus (EBV). In the course of the infection, certain
heterophilic antibodies appear in the patient's serum.
Those antibodies agglutinate horse and sheep erythrocytes.
Specially processed horse erythrocytes are used in
the test. The erythrocyte antigens agglutinate mononucleosis-associated
heterophilic antibodies. The reagent also contains
latex particles to enhance agglutination and facilitate
reading.
The
test is intended for professional use. |
Toxoplasmosis
Direct test
: |
Agglutination
test for the detection of anti-toxoplasma antibodies
in serum. |
|
Toxoplasmosis is a disease caused by protozoan parasite
Toxoplasma gondii. Antibodies are produced during
infection process and they can be detected by the
agglutination of latex beads coated with T. gondii
antigen extract.
This test is intended for professional use.
