Increased levels of ASO titre in the blood could cause damage to the heart and joints. In most cases, penicillin is used to treat patients with increased levels of ASO titre.

What is positive value of ASO titre?

Generally, an ASO test value below 200 is considered normal. In children under the age of 5, the test value should be less than 100. Results will vary by laboratory. If your results show that you have an elevated ASO value, you may have a post-streptococcal complication.

  • Is TCID50 the same as viral titer?

    The assay can be used in two principal ways. First, viral infectivity and the corresponding tissue culture infective dose (TCID) can be determined by serially diluting a virus preparation and applying it to target cell line(s) for a specifi ed exposure period. The virus dilution that produces a cytotoxic endpoint eff ect (i.e., TCID 50
