Breath & Blood Tests in Las Vegas
Breath and blood testing use different procedures. A report may raise questions about device maintenance, observation periods, sample collection, storage, or laboratory methods.
The defense is not a slogan that a machine is unreliable. It is a disciplined comparison of records, timestamps, and the State’s claimed inference.
Understanding the allegation
How Nevada Law Addresses Breath & Blood Tests
NRS 484C.160 through 484C.250 address testing procedures, evidentiary use, and related license consequences. NRS 484C.110 describes different DUI theories.
Compare the time of driving with the time of collection. For breath evidence, review the device and operator records; for blood evidence, review collection, handling, and laboratory methods. The number alone does not resolve every DUI theory.
A concentration result is one part of the evidence. The charged theory and timing of driving and testing must be considered together.
Beyond the initial allegation
What the Test File Can Show
A summary result rarely shows the complete testing process. Breath evidence may involve instrument maintenance, operator records, observation, and the sequence of samples. Blood evidence may involve draw authorization, collection tubes, seals, storage, and laboratory methods.
Create one timeline for driving, officer contact, arrest, and each test. That timeline helps counsel assess what the result can establish under the charged theory and whether the State has the records needed to support its interpretation.
Distinguish a roadside screen from an evidentiary test
NRS 484C.150 treats a preliminary roadside breath test differently from an evidentiary test under NRS 484C.160. The type of device, purpose of the request, time of each sample, and applicable statutory procedure should be identified before comparing numbers or drawing conclusions about what a test proves.

Breath & Blood Tests Frequently Asked Questions

No. The State still must establish the charged offense with admissible, reliable evidence.
Can blood evidence be reviewed independently?
The underlying records can be examined; available retesting depends on the sample and case circumstances.
