On monday a patients hemoglobin determination was 11.3g/dL and on tuesday it measured 11.8 g/dL. the standard deviation of the method used is +/- 0.2 g/dL. what can be concluded about the hemoglobin values given?
there is no significant change in the patient’s hemoglobin concentration
A platelet determination was performed on an automated instrument and a very low value was obtained. the platelets appeared adequate when estimated from the stained blood film. the best explanation for this discrepancy is:
many platelets are abnormally large or platelet clumps
A 14 year old boy is seen in the ER complaining of a sore throat, swollen glands, and fatigue. the CBC results are WBC: 16.0x 10^9/L RBC:4.37 x 10^12 Hgb: 12.8 g/dL Hct:38.4% Platelets:390x10^9/L differential: segs 30% bands 2% lymphs 50% monos 3% Reactive lymphs 15% what is the most likely diagnosis?
A 50-year old man was admitted into the hospital with acute leukemia. Laboratory findings included the following:
Myeloperoxidase ————– Blast cell negative
PAS stain ———————— Blast cells demonstrate a blocking pattern
TdT ——————————– Blast cells positive
Surface immunoglobulin —– Blast cells negative
CD2 ——————————– Blasts cells negative
Philadelphia chromosome —– Positive
These results are most consistent with:
chronic myelogenous leukemia in lymphoblastic transformation

two regular dose vials, +1
Why is an enzyme treatment used in antibody identification?
enzymes aid in the separation and identification of multiple antibodies
