Understanding Hemolysis Index Readings
Reading hemolysis index readings is key for checking blood samples. It tells us if the sample is good and if the results are reliable. We will talk about how to use these values and what different ranges mean.
How to Read Hemolysis Index Values
The hemolysis index shows how much of the blood sample is broken. It comes in numbers. Here’s what the numbers mean:
- Low Values: Means there’s little or no breakage. These are under 10 and show a great sample.
- Moderate Values: Shows average breakage, about 10 to 50. This might need a closer look.
- High Values: If the number is over 50, the blood is broken a lot. This might mess up some test results. We might need to take the sample again.
Common Reference Ranges
Knowing the normal ranges helps us understand if broken blood will affect the tests. This is important for labs and doctors to make the right choices.
| Hemolysis Index Value | Interpretation | Impact on Diagnostics |
|---|---|---|
