How do you read the results of a urine test?
Normal values are as follows:
- Color – Yellow (light/pale to dark/deep amber)
- Clarity/turbidity – Clear or cloudy.
- pH – 4.5-8.
- Specific gravity – 1.005-1.025.
- Glucose – ≤130 mg/d.
- Ketones – None.
- Nitrites – Negative.
- Leukocyte esterase – Negative.
What is cutoff level for drug test?
Urine specimen 9-panel drug test cutoff levels
| Drug | Screen cutoff | Confirmation cutoff |
|---|---|---|
| Amphetamines | 1000 ng/mL | 500 ng/mL |
| Cocaine metabolites | 300 ng/mL | 150 ng/mL |
| Marijuana metabolites | 50 ng/mL | 15 ng/mL |
| Opiates | 2000 ng/mL | 2000 ng/mL |
What does uro mean on a urine test?
A urobilinogen in urine test measures the amount of urobilinogen in a urine sample. Urobilinogen is formed from the reduction of bilirubin. Bilirubin is a yellowish substance found in your liver that helps break down red blood cells. Normal urine contains some urobilinogen.
What does HPF in urine mean?
Bacteria, yeast and parasites If microbes are seen, they are usually reported as “few,” “moderate,” or “many” present per high power field (HPF). Bacteria from the surrounding skin can enter the urinary tract at the urethra and move up to the bladder, causing a urinary tract infection (UTI).
How long does it take to get below 50 ng/mL urine test?
When tested at the 50 ng/ml cutoff threshold, infrequent users typically test negative for the presence of marijuana metabolites within 3-4 days, while heavy users typically test negative by ten days after ceasing use, the study found.
What is urobilinogen in urine 4.0 mean?
Normal urine contains some urobilinogen. If there is little or no urobilinogen in urine, it can mean your liver isn’t working correctly. Too much urobilinogen in urine can indicate a liver disease such as hepatitis or cirrhosis.
What should your urobilinogen level be?
The normal urobilinogen concentration in urine ranges from 0.1-1.8 mg/dl (1.7-30 µmol/l), concentrations >2.0 mg/dl (34 µmol/l) are considered to be pathological. Urobilinogen does not occur in urine, unless bilirubin gets into the intestines.
What is the normal HPF?
A normal result is 4 red blood cells per high power field (RBC/HPF) or less when the sample is examined under a microscope.
Is mg/l the same as ng ml?
mg/L↔ng/ml 1 mg/L = 1000 ng/ml.
