Anti-streptolysin O (ASO or ASLO) is the antibody made against streptolysin O, an immunogenic, oxygen-labile streptococcal hemolytic exotoxin produced by most strains of group A and many strains of groups C and G Streptococcus bacteria. The "O" in the name stands for oxygen-labile; the other related toxin being oxygen-stable streptolysin-S.
Antiphospholipid syndrome is known for causing arterial or venous blood clots, in any organ system, and pregnancy-related complications.While blood clots and pregnancy complications are the most common and diagnostic symptoms associated with APS, other organs and body parts may be affected like platelet levels, heart, kidneys, brain, and skin.
Thus, if the initial titer is 1:4 and stable but increases at 26 weeks' gestation to 1:8, assessment with MCA Doppler velocity at that point is reasonable. However, if the patient presents in the first trimester with a 1:8 titer that remains stable at 1:8 throughout the second trimester, continued serial antibody titers are appropriate.
One study found that men with moderate-to-high levels of exhaustion had a 2.7-fold increased risk of heart attack within five years and a 2.25 higher risk within ten years. The study also found a ...

Titers of 1:4 or higher is considered critical for Kell (compared to 1:16 for most other antibodies) and is considered to confer a high risk of fetal anemia. [17] Such high titers may be managed by weekly follow-up by obstetric ultrasound , assessing the peak systolic velocity of the fetal middle cerebral arterial (MCA), amniotic fluid volume ...
Post-streptococcus glomerulonephritis is more often associated with group A strep skin infection than it is with strep pharyngitis, so in a patient with suspected post-strep glomerulonephritis with a negative ASO titer, one can then obtain anti-DNase-B titers which are more sensitive for group A strep and for its various strains.
This may include a full blood count (FBC), erythrocyte sedimentation rate (ESR), antistreptolysin-O (ASO) titer and throat culture, urinalysis, intradermal tuberculin test, and a chest x-ray. [22] The ESR is typically high, the C-reactive protein elevated, and the blood showing an increase in white blood cells.
