What is the classification for low serum calcium levels?

The classification for low serum calcium levels is referred to as hypocalcemia. This condition arises when the calcium concentration in the blood falls below the normal range, which typically is around 8.5 to 10.2 mg/dL in adults. Hypocalcemia can result from various factors, including parathyroid gland disorders, vitamin D deficiency, or certain medications, and can lead to symptoms such as muscle spasms, tingling sensations, or even more severe consequences like cardiac arrhythmias if not addressed.

Understanding hypocalcemia is crucial because calcium plays vital roles in numerous biological processes, including neuromuscular function, blood coagulation, and the maintenance of bone health. Correctly identifying and classifying this condition allows healthcare providers to implement appropriate management and treatment strategies to restore serum calcium levels to a normal range.
