To answer this question, let's analyze the given critical test result values for glucose and define them clearly.
### Understanding the Given Ranges:
1. Range 1: 20 - 600 mg/dL
- This range indicates that glucose levels between 20 and 600 mg/dL are being considered as critical values.
2. Range 2: <40 and >500 mg/dL
- Here, this specifies two separate critical ranges:
- Glucose levels less than 40 mg/dL.
- Glucose levels greater than 500 mg/dL.
3. Range 3: 50 - 400 mg/dL
- This range indicates that glucose levels between 50 and 400 mg/dL are critical.
4. Range 4: 70 - 120 mg/dL
- This specifies that the critical glucose range is between 70 and 120 mg/dL.
### Summarizing the Critical Ranges:
To consolidate these ranges, we'll list each set of critical values separately:
1. [tex]\( 20 \leq \text{glucose} \leq 600 \)[/tex] mg/dL
2. [tex]\( \text{glucose} < 40 \)[/tex] mg/dL or [tex]\( \text{glucose} > 500 \)[/tex] mg/dL
3. [tex]\( 50 \leq \text{glucose} \leq 400 \)[/tex] mg/dL
4. [tex]\( 70 \leq \text{glucose} \leq 120 \)[/tex] mg/dL
### Interpretation of Critical Ranges:
- Range 1 indicates a broad range of critical glucose values from 20 mg/dL to 600 mg/dL.
- Range 2 identifies glucose levels as critical when they are extremely low (less than 40 mg/dL) or very high (greater than 500 mg/dL).
- Range 3 marks glucose levels between 50 mg/dL and 400 mg/dL as critical, a range embedded within the first set.
- Range 4 specifically indicates critical glucose levels within a more restricted range, between 70 mg/dL and 120 mg/dL.
### Conclusion:
After understanding and interpreting the provided glucose ranges, we can clearly state that the critical test result values for glucose are:
- 20 to 600 mg/dL
- Less than 40 mg/dL or Greater than 500 mg/dL
- 50 to 400 mg/dL
- 70 to 120 mg/dL
These ranges represent various critical levels for glucose that may require different attention or medical intervention based on their severity.
