Interpret Toxicology Evidence
Compare toxicology results to cutoffs and controls before making an evidence claim.

Compare toxicology results to cutoffs and controls before making an evidence claim.
Step 1: Learn the key
A toxicology result is interpreted by comparing the sample value to the [blank] and checking whether the [blank] worked.
| Substance | Result | Reference limit |
|---|---|---|
| Drug A | 4 ng/mL | under 5 = negative |
| Drug B | 18 ng/mL | 10 or more = positive |
| Control | expected | valid run |
Step 2: Use the model
Read the figure, table, control, range, or protocol before choosing an answer.
Step 3: Name the limit
Say what the evidence can support and what it cannot prove yet.
Practice
Use the toxicology table. Which substance is below its reference limit?
Reviewed| Substance | Result | Reference limit |
|---|---|---|
| Drug A | 4 ng/mL | under 5 = negative |
| Drug B | 18 ng/mL | 10 or more = positive |
| Control | expected | valid run |
- A.Drug A
- B.Drug B
- C.The control row
- D.The table title
Show the worked solution ▾
Answer: A. Drug A
- Step 1: Read Drug A: Drug A is 4 ng/mL.
- Step 2: Compare limit: Under 5 is negative; 4 is below 5.
Why it's right: Drug A is below its listed reference limit.
Why the others miss:
- B: Drug B is 18 with positive cutoff 10.
- C: The control checks validity.
- D: Title is not a substance.

Guided notes
Fill these in as you work through the lesson.
Big idea: Compare toxicology results to cutoffs and controls before making an evidence claim.
Key terms: write the meaning
- Toxicology (testing for drugs, poisons, or chemicals):
- Cutoff (value used to call positive or negative):
- Control (known check that test worked):
- Positive result (target is at or above the cutoff):
The rule
A toxicology result is interpreted by comparing the sample value to the and checking whether the worked.
Check yourself
- What is the sample value?
- What is the cutoff?
- Did the control behave as expected?
Work one example
Drug B is 18 ng/mL and cutoff is 10 ng/mL. Write the result and one limitation.
