To calculate the adjusted calcium level:
\[ \text{AC} = C + 0.8 \times (4 - P) \]
Where:
Adjusted calcium, also known as corrected calcium, is used to more accurately reflect the amount of free, active calcium in the body by accounting for variations in albumin levels. Since calcium binds to albumin, changes in albumin levels can affect the total calcium measurement. The adjusted calcium level helps provide a clearer picture of calcium status in patients, especially when albumin levels are abnormal.
Assume the following values:
**Step 1:** Calculate \( 4 - P \)
\[ 4 - 3.2 = 0.8 \]
**Step 2:** Multiply the result by 0.8
\[ 0.8 \times 0.8 = 0.64 \]
**Step 3:** Add this value to the measured total calcium level
\[ \text{AC} = 9.5 + 0.64 = 10.14 \]
The Adjusted Calcium Level is 10.14 mg/dL.
Assume the following values:
**Step 1:** Calculate \( 4 - P \)
\[ 4 - 4.0 = 0 \]
**Step 2:** Multiply the result by 0.8
\[ 0.8 \times 0 = 0 \]
**Step 3:** Add this value to the measured total calcium level
\[ \text{AC} = 8.7 + 0 = 8.7 \]
The Adjusted Calcium Level is 8.7 mg/dL.
