At equivalence the area of the ring is proportional to antigen concentration. For example-Dilution ASO iuml Neat 200 12 400 14 800 18 1600 ASO titers 200iuml are found in 95 of the healthy adult population being that value higher up to 300iuml among.

Antigen diffuses from the well into the gel and forms a precipitin ring by reaction with antibody. The ASO titer was negative while the Streptozyme test is positive. To each of the remaining tubes 2 to 8 add 10 ml of isotonic saline.

The approximate ASO level IUml present in the sample can be optained by the following formula. Pipette one drop 50 μL of ASO Positive Control on field 1 of the reaction slide and one drop 50 μL of the ASO Negative Control on field 2 of the reaction slide. If the agglutination is present up to a titre 14 the approximate serum ASO level is 4 x 200 800 IUml.

The median ASO titers in acute pharyngitis group and ARF were significantly raised compared to that of the control group. See answer 1 Best Answer. If youve accidentally put the card in the wrong box just click on the card to take it out of the box.

They may get higher for several weeks before decreasing. ASO titers that are initially high and then decline suggest that an infection has occurred and may be resolving. An elevated titer of antibody positive ASO or an ASO titer that is rising means that it is likely that the person tested has had a recent strep infection.

In this study 660. Use an applicator stick to mix the two drops and spread them over the entire well. Dilute the serum 1.
