Direct coombs test was positive and
indirect coombs test was negative.
Gold standard for diagnosis of neurobrucellosis is positive CSF culture, yet its yield is often low being positive in <25% in most cases.4 Diagnosis is confirmed by detection of specific antibodies in CSF using ELISA,
indirect coombs test or standard agglutination techniques.5 In both presented cases, CSF culture showed no growth after 6 weeks of incubation and diagnosis was made by detection of brucella antibodies in blood and CSF using standard agglutination technique.
Indirect Coombs test in the mother and anti-E antibody levels in the mother and baby were positive.
The
indirect coombs test is used to detect antibodies in the patient's sera by using red blood cells with known antigens on their surfaces [24].
The
indirect Coombs test was devised to seek the presence of incomplete antibodies in the patient's serum.
Sometimes free antibody can be demonstrated in the serum (
indirect Coombs test).3 In suspected cases of AIHA, a positive DAT is predictive in 83% of patients, but not all cases of AIHA are DAT positive.
Direct and
indirect Coombs test results were negative.
(d) Indirect bilirubin level, 2.1 mg/dL; serum haptoglobin level, <38 mg/dL (normal range, 60-160 mg/dL): results of direct and
indirect Coombs test, negative.
LDH)-1737 U/L, direct and
indirect Coombs test positive, hemoglobin in urine--0.88g/dl, Glucose 6-Phosphate dehydrogenase (G6PD) not deficient, osmotic fragility-within normal limits, serum.vitamin [B.sub.12] was 234 pg/ml (180-934 pg/ml), serum folate was 5.62 ng/ml.
