The Following Hemoglobin Results,reported in G/dL,are Obtained on a Hospitalized $\frac{\text { Day 1 }}{14.3} \quad \frac{\text { Day } 2}{11.5} \quad \frac{\text { Day } 3}{144}$

question 19

Multiple Choice

The following hemoglobin results,reported in g/dL,are obtained on a hospitalized patient on 3 consecutive days:
$\frac{\text { Day 1 }}{14.3} \quad \frac{\text { Day } 2}{11.5} \quad \frac{\text { Day } 3}{144}$
The SD for this hemoglobin method was calculated in Question 18.A delta check was obtained on day 2.Controls were run as appropriate each day and were all within limits for this procedure.
What is the most probable reason for the day 2 result when compared with those for days 1 and 3?

• A)It is within the 95.5% confidence levels for this test.
• B)It may represent an error in patient identification.
