What is the False Negative Pregnancy Test Calculator & How does it work?
A false negative pregnancy test occurs when a pregnancy test incorrectly indicates that a woman is not pregnant, even though she actually is. This can happen due to various factors such as testing too early in the pregnancy or issues with the test itself.
The probability of a false negative can be influenced by several variables including the sensitivity of the test, the timing of the test relative to conception, and hormonal levels. Understanding these factors helps in interpreting the results accurately.
P(text{False Negative}) = 1 – frac{text{True Positives}}{text{Total Positives}}
P(False Negative) = Probability of a false negative result
True Positives = Number of actual pregnancies correctly identified as positive
Total Positives = Total number of tests that returned positive results
True Positives = Number of actual pregnancies correctly identified as positive
Total Positives = Total number of tests that returned positive results
