Elevated ASO titers are found in the sera of about 85 of individuals with rheumatic fever.

Aso titer normal values i nu ml. Normal value ranges may vary slightly. Geometric mean titer and Upper Limit of Normal of ASO were calculated according to sex age and residency. Limit of normal ASO titers for preschool children is less than 100 IUml and in school age children or young adults is usually between 166 and 250 IUml.

Results will vary by laboratory. The ASO ULN for both male and female children were 320 IUml with a median of 200 IUml. All serum samples were analyzed collectively by nephelometric method.

The upper limit of normal value for anti-DNase B has been defined by separating the upper 20 from the lower 80 of all measurements. Out of 267 participants. The highest level of ASO is seen in glomerulonephritis and rheumatic fever.

The ASO ULN serum level for total adult population in Aleppo is 210 this finding is higher than the results of studies in Georgia 11 Korea 12 India 13 Australia 14 and Uganda 15 Table 3. Anti-streptolyasin O ASO serum titer in excess of 200 IUml is considered abnormally high and suggest either recent infection with streptococci or persistently high antibody level due to earlier exposure in hypersensitive persons. 126 457 were males and 150 543 were females.

In uncomplicated cases the titer usually drops to a normal level 8 to 10 weeks after clinical symptoms subside. 12 ASO TITER NORMAL VALUES The normal values of the ASO titer are less than 160 Todd unitsml in adults less than 50 Todd unitsml in children from six months to two years less than 160 Todd unitsml in children from two to four years less than 170-330 Todd unitsml in chil-dren from fi ve to 12 years. Discussion The diagnostic criteria of rheumatoid heart disease is ASO level greater than 200 IUml.

The Upper Limit of Normal for total participants was 2108 IUml. Although the antistreptolysin O ASO test is quite reliable performing the anti-DNase is justified for 2 primary reasons. Very low or normal ASO titers may be found in skin infections and their sequelae.

A fourfold rise in the titer is significant for acute and convalescent patients. A negative test result means that you do not have strep infection. If the agglutination is present up to a titre 14 the approximate serum ASO level is 4 x 200 800 IUml.

Limit of normal reference values for ASO titer according to sex and age groups of enrolled subjects. 6 rows The estimated titers that were 80 of the upper limit or normal at age 10 years were 276 IUml. When analyzed according to age groups anti-DNase B antibody.

The ASO ULN for the total subjects was 360 IUml with a median 200 IUml. Because of this variation titers above the upper limits may be indicative of a streptococcal infection. Your health care provider may do the test again in 2 to 4 weeks.

In children under the age of 5 the test value should be less than 100. Therefore the Anti DNAse B test is preferred in diagnosing. Adult elderly 160 Todd unitmL or Todd units mL 5 to 12 years 170 to 330.

Mosbys Diagnostic and Laboratory Test Reference 2019 book determined the normal findings of ASO titer for Adults and elderly less than 160 Todd unitsml. In our study a total of 123 patients of RHD were. The 500 to 5000 Todd unitsmL level suggests acute post-streptococcal glomerulonephritis rheumatic fever or acute poststreptococcal endocarditis.

The highest ASO ULN was observed for the age group of 9-12 years 400 IUml. ASO Titre IUml Highest dilution with positive reaction x Reagent sensitivity 200 IUml eg. Anti-DNase B antibody levels were ranged between 50-576 IUml and its upper limit was 2192 IUml.

An elevated ASO titer appears 1 to 3 weeks after infection with a group A streptococcus. Generally an ASO test value below 200 is considered normal. First the ASO response is not universal.

The antistreptolysin O titer measures the level of antistreptolysin O antibodies in the blood plasma. ASO titers remain normal in about 15 of individuals with the disease. Normal findings for antistreptolysin O titers.

In any case the average can be established at less than 200 IUml. Limitations of the Test. The approximate ASO level IUml present in the sample can be optained by the following formula.
