MICHIGAN INNOVATIVE DIAGNOSTICS

Screens for urinary tract, renal, and metabolic abnormalities via chemical dipstick analysis of urine, followed by microscopic examination of urine sediment.

​​​

​

INDIVIDUAL LIS TEST CODES INCLUDED WITHIN PANEL: COLOR, CLARITY, GLU, KET, BIL, SG, PH, PRO, BLO, URO, NIT, LEU, WBCS, RBCS, BACT, EPIS, CASTS, EPIT, EPIR, CASTC, CASTG, CASTW, YEAST, MUCUS, CRYU, CAOX, STRU, CRYAM, CRYCH, CRYSIS, CRYT, CRYBIL, HIPUR, CACARB, MUCRY, AMORPH, LIPUR, SPERM, TRICH

​

CPT CODE: 81001

​

ALIASES: Complete UA, Urinalysis with Microscopic, Macro/Micro Urinalysis

​

METHODOLOGIES: Reflectance Photometry (Colorimetry), Manual Microscopy

​

SPECIMEN:

​

- Type: Clean-Catch Urine

​

- Container: Urine Container (Plain Yellow/Speckled Top)

​

- Minimum Volume Required: 3 mL

​

- Storage/Handling: Specimen should be capped tightly and transported to the laboratory promptly. If testing cannot be performed within the stability window listed below, refrigerate immediately.

​​

NOTE: Do NOT centrifuge or add preservative unless otherwise instructed; refrigeration is preferred over freezing, as freezing destroys formed elements needed for microscopic exam.

​

- Stability:   

 

Room Temperature (20-25 °C): 2 hours

Refrigerated (2-8 °C): 1 day

Frozen (-20 °C or colder): Not Accepted

​

- Turnaround Time: 24 hours from receipt.

​

Special Instructions: Patients should be instructed to collect a clean-catch, midstream sample when infection is suspected, to minimize contamination from external flora, using the following procedure:

​

1. Wash hands thoroughly with soap and water before collection.

2. Cleanse the genital area from front to back using the provided antiseptic wipe(s):

   • Females: Spread the labia and wipe from front to back on each side, then down the middle.

   • Males: Retract the foreskin (if uncircumcised) and wipe the tip of the penis in a circular motion.

3. Begin urinating into the toilet, allowing the first portion of the stream to pass.

4. Without stopping the stream, collect a midstream sample directly into the sterile specimen cup, avoiding contact between the cup and skin.

5. Finish urinating into the toilet, then securely cap the specimen cup.

 

First-morning specimens are preferred for microalbumin or protein evaluation due to increased concentration.

​

REJECTION REASONS: Excessive Mucus, Color Interference, QNS, Contamination, Stability Violation, Expired Container, Incorrect Container

​

INTERPRETING ABNORMAL QUALITATIVE FINDINGS:

​

"None seen" = Absent = 0 / field

​

"Rare" = Trace = 1 - 2 / field

​

"Few" = 1+ (+) = 3 - 10 / field

​

"Moderate" = 2+ (++) = 11 - 25 / field

​

"Many" = 3+ (+++) = 26 or more / field​​

​

"Present" = target element was observed at least once in two separate fields during microscopic exam.

​

Panic Threshold(s): Ketones >= 3+ (ONLY IF Glucose, Urine is also >= 1+) for Males and Females >= 1 year of age.
