ELISA (Enzyme-Linked Immunosorbent Assay) in Hematological Disorders

Image
  1. Objective The objective of the experiment was to detect and quantify disease-specific antigens or antibodies in hematological disorders using the ELISA technique. 2. Principle The ELISA technique was based on antigen-antibody interaction. Either the antigen or antibody was immobilized on a solid surface (usually a microtiter plate), and a corresponding enzyme-labeled antibody was used for detection. Upon addition of a chromogenic substrate, a color change occurred, which was measured spectrophotometrically and correlated with the concentration of the target molecule. 3. Materials Used Microtiter ELISA plate Patient serum or plasma samples Known standards and controls Enzyme-conjugated antibodies (e.g., anti-FVIII for Hemophilia A) Substrate (e.g., TMB – Tetramethylbenzidine) Stop solution (e.g., sulfuric acid) Plate washer and reader Pipettes and sterile tips 4. Procedure The microtiter plate was coated with capture antibody and incubated....

Antiphospholipid Antibody Test (e.g., dRVVT)

Image
  1. Objective: To detect antiphospholipid antibodies in patient plasma, especially in suspected cases of antiphospholipid syndrome, using the Dilute Russell’s Viper Venom Time (dRVVT) test. 2. Principle: The dRVVT measures the time it takes for plasma to clot after the addition of diluted Russell's viper venom, which directly activates factor X. In the presence of antiphospholipid antibodies, especially lupus anticoagulant, the clotting time is prolonged. A confirmatory test with excess phospholipids is used to demonstrate correction. 3. Materials Required: Patient citrated plasma Normal pooled plasma (control) Russell’s viper venom reagent (screening and confirmatory) Calcium chloride Platelet-poor plasma Coagulometer or water bath with stopwatch Test tubes and pipettes 4. Procedure: Collected citrated blood and prepared platelet-poor plasma. Added venom reagent to both patient and control plasma. Added calcium chloride to initiate clottin...

Antibiotic Sensitivity Test

Image
  1. Objective The objective of this test was to determine the  sensitivity of bacterial isolates  to various  antibiotic agents , helping guide effective antimicrobial therapy.   2. Principle The test was based on the  inhibition of bacterial growth  by antibiotics. The  Kirby-Bauer disc diffusion method  was used, where antibiotic-impregnated discs were placed on an agar plate inoculated with bacteria. The  zone of inhibition  around each disc indicated the effectiveness of the antibiotic. 3. Materials Pure bacterial isolate Mueller-Hinton agar plates Antibiotic discs (e.g., ampicillin, ciprofloxacin, ceftriaxone) Sterile swabs  McFarland standard (0.5) Incubator (35–37°C) Ruler or caliper CLSI guideline chart for interpretation 4. Procedure A standardized bacterial suspension (0.5 McFarland) was prepared. The suspension was evenly spread onto Mueller-Hinton agar using a sterile swab.
