Hair drug tests are used by employers who have zero tolerance drug use policies, courts and individuals on probation. The primary advantage of a hair drug test is that it includes a much longer detection period for drug use which typically is up to 90 days. However, when screening for drug use within the last 5 days the urine test continues to be the most accurate test.

Hair drug testing is the only method available that provides up to a 90-day look back period for drug use.  Data has shown that hair drug testing provides almost twice the number of positives because of its longer window of detection (look back period). If a donor has no hair on their body, then a hair test cannot be performed!

The city had an estimated population of 86,685 in 2017. The Port of Redwood City is the only deepwater port on San Francisco Bay south of San Francisco. Redwood City is the location of the San Mateo County Jail, for both women and men.
