Two theoretical models are presented. Model 1 (turbid/gel clot); healthy human WBCs (8-10000 μl) are put into assay tubes (12 × 75 mm) in 200 μl solution of mono and divalent cations + urea + 0.0125 g of potassium iodate + Tris buffer (0.001M) + MgCl2 (0.05 M) at pH 7-8 range, exposed to throat swabs and incubated for 1-6 hrs at 27°C. In +ve cases the assay the solution turns turbid or gels (0.0125 g of potassium iodate may be added for select area pigmentation). (CH2COO)2Ca 10% is used to reverse the turbidity as counter validation of a +ve result exclusively. Model ii (ground glass effect). WBCs + solution as above pour on plain glass slide air dry slowly in humid-moist incubator for 1-24 hrs. Convenient-Economic-Mass Ultra Rapid Covid Test.
