Background: Blood status is closely related to the hemoglobin test results in clinical laboratory. This paper discusses a case of which hemoglobin test results were not interfered by the “milky” blood status.
Methods: Complete Blood Count with Differential (CBC + Diff) was detected for these two specimens with a Sysmex XN-9000.
Results: The results of red cell indices for patient I were as follows: red blood cell count (RBC), 5.10 x 1012/L; hematocrit (HCT), 0.455 L/L; hemoglobin (HGB), 167 g/L; mean corpuscular hemoglobin concentration (MCHC), 367 g/L, and triglycerides (TG), 1.59 mmol/L. There was no “turbidity” warning message. However, there was a “turbidity” warning message for patient II and his red cell indices were RBC, 4.74 x 1012/L; HCT, 0.492 L/L; HGB, 182 g/L; MCHC, 370 g/L, and TG, 12.98 mmol/L. After the plasma exchange, there was no “turbidity” warning message for patient I and his red cell indices were RBC, 4.83 x 1012/L; HCT, 0.444 L/L; HGB, 164 g/L; MCHC, 369 g/L which were consistent with the results before the plasma exchange. For patient II, the “turbidity” warning message disappeared and his results were RBC, 3.87 x 1012/L; HCT, 0.398 L/L; HGB, 135 g/L; MCHC, 339 g/L.
Conclusions: Our case provided an explanation of the normal hemoglobin detection results in the visible lipemic specimen for the first time.
