Which cord blood value is considered out of the normal range?

The value of 40,000/mm3 for cord blood is considered out of the normal range because typical normal platelet counts in cord blood are generally observed to be between 150,000 to 450,000/mm3. A platelet count of 40,000/mm3 indicates thrombocytopenia, which is a significantly low platelet count, placing the newborn at increased risk for bleeding complications.

Understanding normal laboratory ranges is crucial in neonatal care, as it helps healthcare providers identify potential health concerns promptly. Identifying abnormal values, such as low platelet counts, is important in managing care effectively for neonates, especially those who may already be at risk due to factors such as prematurity, maternal conditions, or other medical complications.

In contrast, other values like 10,000/mm3, 30,000/mm3, and 20,000/mm3, while possibly also low, do not surpass the threshold set by 40,000/mm3 for identifying thrombocytopenia as a critical issue in neonatal health. Therefore, a count of 40,000/mm3 stands out as not just low but critically so, warranting immediate attention and intervention.
