TECHNICAL FIELD OF THE INVENTION
[001] The disclosed subject matter relates generally to an automatic system and process for detecting agglutination. The present invention relates to an agglutination device to detect Blood Group, Bacteria, Virus and proteins in whole blood samples or plasma or serum for rapid and early detection. More particularly, the present disclosure relates medical field for detection of agglutination at point of care according to preloaded reagents and arrangment.
BACKGROUND OF THE INVENTION
[002] Generally it will take more time and much more human effort to diagnose any blood related tests or in any other means. Detection of antigen/antibodies in a fluid test sample is one of the widely practicing technique in the field of biological reasearch and development of human and veternery medicine based up on particle agglutination, including latex particle agglutination in biomolecule detection assays processs. Eventhough agglutination assay procedures have advantages of being simple, widely applicable, and nonhazardous and also generally rapid, producing results in a short time, whereas they are lack in Exact detection in sharp colour development and/or requirements of large volumes of sample due to which agglutination assays are typically overlooked for analytical purposes in favor of enzyme-linked immunosorbent assays (ELISA).
[003] Currently, various following techniques are available in the market for the determination of agglutination such as:
US9244065B1 entitled "Systems, devices, and methods for agglutination assays using sedimentation" discloses methods for conducting agglutination assays using sedimentation. Aggregates may be exposed to sedimentation forces and travel through a density medium to a detection area.
US8211365B2 entitled "Immunodiagnostic test cards having indicating indicia" discloses an immunodiagnostic test card includes a plurality of transparent chambers wherein each chamber includes a quantity of testing material that combines with a patient sample, when mixed, to produce an agglutination reaction. A plurality of indicia are disposed to aid in the manufacture and determining the usability of the cards prior to test and also in objectively grading the agglutination reactions that are formed or lack of agglutination.
WO1999051982A3 entitled "Method for automated erythocytic blood group determination" discloses a method for erythocytic blood group determination, whereby commercially available disposable microtiter plates with a pointed bottom are used to an advantageous effect. Albumin is added to the antiserum in such a way that the concentration of albumin amounts to 0.05-2.2 mg/ml, preferably 0.2 1.0 mg/ml. This process corresponds to a traditional sedimentation method without any centrifugal phase or sample shaking phase. Sample preparation can be easily automated, especially when known types of pipetting machines are used. Sedimentation images show a clear difference between positive and negative reactions. Evaluation, especially in the case of photometric optical evaluation of sedimentation images, is easy from a technical point of view and the inventive method can be automated in a reliable manner. As a result it is possible to obtain a high sample through-flow with very few errors for a low cost in terms of material outlay.
US5413913A entitled "Erythrocyte agglutination assay" discloses an erythrocyte agglutination assay, the agglutination reagent comprises at least one erythrocyte binding molecule coupled to at least one specific analyte binding molecule wherein the erythrocyte binding molecule does not cause agglutination when incubated with erythrocytes in the absence of analyte (in the case of a direct assay) or analyte binding reagent (in the case of an indirect assay). Preferably, the erythrocytes are endogenous to the blood sample to be tested, that is, a whole blood sample is assayed. Mixtures of conjugates and conjugates of analyte analogues with erythrocyte binding molecules may also be used as agglutination reagents. The reagents and their use in direct or indirect assays is disclosed.
EP2833146A1 entitled "Latex particles for agglutination assay" discloses A latex particle for high-sensitive agglutination assay and a reagent for agglutination assay including the particle are provided. The latex particle barely initiates non-specific reactions and can readily prepare diagnostic agents. A latex particle for agglutination assay including a polymerizable monomer having a phenyl group, a polymerizable monomer having a phenyl group and a salt of sulfonic acid, and a polymerizable monomer represented by Formula (1):
CH2=CR1-COO(CH2CH2O)n-R2 (1)
where R1 represents a hydrogen atom or a methyl group; R2 represents a hydrogen atom or a methyl group; and n is 1=n<20, wherein the density of functional groups derived from the polymerizable monomer represented by Formula (1) on the surface of the particle is 0.05 to 0.5 µmol/m2.
[004] And also, Typhoid is an endemic febrile disease caused by Salmonella typhi. Typhoid is a major concern of public health. The organism usually enters the body by consumption of contaminated food or water and penetrates the intestinal wall. After that it multiplies and enters blood stream within 24-72 hours resulting in enteric fever and bacteremia. After an incubation period of 10 to 14 days, early symptoms of typhoid, like headache, fever, loss of appetite, bradycardia, splenomegaly etc. appear. Typhoid is diagnosed either by blood culture or by detection of its antigens or by the detection of its antibodies in the blood.
[005] One of the most adapted methods for diagnosing the typhoid fever is the performance of "Widal test", a serological test based on the detection of antibodies in the blood. This test is based on the fact that antibodies against typhoid, remain in the blood of infected person, bind to the bacteria and results in the clumps formation which is referred as "Widal Agglutination".
[006] Major limitation of aforesaid techniques is that they require sophisticated and elaborate laboratory facilities which includes skilled manpower, pipettes, tips, slides, centrifuge to perform limiting their use in view of resource limited settings.
[007] And also in all the existing technologies, technician has to expose to samples and reagent during and after test, which may lead to unwanted problems to technician.
[008] One of the important limitation in the present generation of all aforesaid techniques is that, they requires minimum 4-5 hours to perform the tests and to receive results.
[009] Another important limitation in aforesaid techniques is that, they analyze only single assay either related to blood or serum or analysis of infections, but unable to perform multiplexity at a time.
[010] In the light of the aforementioned discussion, there exists a need for an automatic system and process for detecting agglutination with novel techniques that would overcome the above-mentioned disadvantages and address the needs for specific industries.
[011] Hence in light of aforesaid there exists need of an automatic system and process for detecting agglutination which does not require sophisticated and elaborate laboratory facilities which includes skilled manpower, pipettes, tips, slides, centrifuge to perform limiting their use in view of resource limited settings.
[012] Hence in light of aforesaid there exists need of an automatic system and process for detecting agglutination which does not require reagents which are highly expensive.
[013] Hence in light of aforesaid there exists need of an automatic system and process for detecting agglutination which gives results within fraction of minutes.
[014] Hence in light of aforesaid there exists need of an automatic system and process for detecting agglutination which perform multiplexity of ABO Blood Grouping, Analysis of bacterial and viral infections, fevers and sexually transmitted diseases, and also detection of proteins, bacteria and viruses in blood samples at a time.

? Reagents Used:
The automatic-agglutination device for ABO Blood grouping consists of 4 reagent chambers as shown in Fig.1100A.
ABO Blood Grouping consists of following three reagents:
(a) Anti-A (IgM) Antibody,
(b) Anti-B (IgM) Antibody and
(c) Anti-D (IgM) Antibody.
? Quantities of Reagents and materials used:
• Reagent chamber 1 consists of 500ul of Anti-A (IgM) Antibody.
• Reagent chamber 2 consists of 500ul of Anti-B (IgM) Antibody.
• Reagent chamber 3 consists of 500ul of Anti-D (IgM) Antibody.
• Reagent chamber 4 consists of 500ul of PBS which acts as a control for lack of agglutination.
• The automatic-agglutination device consists of capillary tube with 1mm ID and 6mm length, this has a sample capacity of 4.7ul/capillary tube.
? Assay Procedure:
ABO Blood Grouping was performed by following steps:
1. Firstly finger is cleaned with alcohol swab and pricked with a pricking needle.
2. Capillary cap was removed from the device.
3. All four capillary tubes are brought into contact with blood drop on the finger while piston is in compressed state.
4. Once the sample is taken up by capillary tubes, piston was released to transfer the sample from capillary tube to reagent chamber.
5. Then capillary cap was placed back on the device.
6. Automatic agglutination device was tilted gently at an angle for 3-5 times.
7. The agglutination result observed from top view through transparent top panel of the device.
8. The results of the agglutination were shown in Fig.1100B.
? Result:
From the Fig.1100B agglutination was clearly seen in Reagent chamber 1 and Reagent chamber 3 indicating that the sample is A+. The presence of false positive is ruled out by the lack of agglutination in Reagent chamber 4.
