U1 RPN (snRNP)Antibodies, Serum

Test Code: 7118 CPT Code: 86235
Specimen Type: Serum collected in a yellow-top tube
Sample Volume: 3.0 mL (1.0 mL - min)
Transport Condition: Refrigerated condition
Specimen Rejection Criteria: Gross hemolysis
Methodology: Immunoassay
Special Requirements: No special precautions needed
Clinical Significance:

U1 RNP antibodies in combination with Smith antibodies provides additional support for the diagnosis of SLE. A positive U1 RNP antibodies alone with the corresponding clinical history supports the diagnosis of mixed connective tissue disease.

Urea, 24 Hrs, Urine

Test Code: 317 CPT Code: 84540
Specimen Type: 24 hrs urine in sterile leak proof container
Sample Volume: 10 mL
Transport Condition: Refrigerated condition
Specimen Rejection Criteria: Nil
Methodology: Spectrophotometry
Special Requirements: 24 hrs urine with 10 g boric acid. Mention 24 hrs urine volume.
Clinical Significance:

Urea, a major end product of protein metabolism, is freely filtered by glomeruli. The majority of it is excreted into the urine, although variable amounts are reabsorbed along the nephron. This assay aids assessment of protein intake and/or nitrogen balance.

Run Day: Daily
Reporting Day: Same day

Urea, Serum

Test Code: 318 CPT Code: 84520
Specimen Type: Serum collected in a yellow-top tube
Sample Volume: 3.0 mL (1.0mL - min)
Transport Condition: Room temperature

Urea is the end product of protein metabolism. Important component of Renal Function Test.

Run Day: Daily
Reporting Day: Same day

Ureaplasma, Culture & Sensitivity

Test Code: 9952 CPT Code: 87109
Specimen Type: Urethral, vaginal, cervical swabs (dry or with media acceptable but preferred with media)/ semen in sterile leak proof container
Sample Volume: 1-2 mL or 1to 2 swabs
Transport Condition: Room temperature
Specimen Rejection Criteria: Inappropriate specimen transport device, mislabeled specimen, unlabeled specimen
Methodology: Culture & Sensitivity
Special Requirements: Not Applicable
Clinical Significance:

U parvum is usually the commonest species detected in various clinical specimens but U urealyticum is probably more pathogenic in conditions such as male urethritis. In humans,
both Mycoplasma and Ureaplasma species may be transmitted by direct contact; venereally through genital-to-genital or oral-to-genital contact, vertically from mother to offspring either at birth or in utero, or by nosocomial acquisition through transplanted tissues. U urealyticum and M genitalium are causes of non-chlamydial non-gonococcal urethritis in men.

Run Day: Daily
Reporting Day: 2 weeks

Uric Acid, 24 Hrs, Urine

Test Code: 16320 CPT Code: 84560
Specimen Type: 24 hrs urine
Sample Volume: 5 mL
Transport Condition: Refrigerated condition
Specimen Rejection Criteria: Nil
Methodology: Spectrophotometry
Special Requirements: 24 hrs urine with 5% sodium hydroxide. Mention 24 hrs urine volume.
Clinical Significance:

Uric acid is the end-product of purine metabolism. It is freely filtered by the glomeruli and most is reabsorbed by the tubules.There is also active tubular secretion. Urine uric acid levels reflect the amount of dietary purines and also endogenous nucleic acid breakdown. This assay aids in assessment and management of patients with kidney stones, particularly uric acid stones.

Run Day: Daily
Reporting Day: Same day

Uric Acid, Random, Urine

Test Code: 319 CPT Code: 84560
Specimen Type: Urine in sterile leak proof container
Sample Volume: 10 mL
Transport Condition: Room temperature
Specimen Rejection Criteria: NA
Methodology: Spectrophotometry
Special Requirements: No special precautions needed
Clinical Significance:

Urine uric acid may supplement serum uric acid testing in investigating conditions in which there is alteration of uricacid production or excretion eg., gout, leukemia, renal diseases. The information about amount of uric acid excreted may be useful in treating asymptomatic hyperuricemia. Measurement of urine uric acid is important in the investigation of urolithiasis.

Run Day: Daily
Reporting Day: Same day

Uric Acid, Serum

Test Code: 1095 CPT Code: 84550
Specimen Type: Serum collected in a yellow-top tube
Sample Volume: 3.0 mL (1.0mL - min)
Transport Condition: Refrigerated condition
Specimen Rejection Criteria: Gross hemolysis
Methodology: Spectrophotometry
Special Requirements: No special precautions needed
Clinical Significance:

Serum uric acid measurements are useful in the diagnosis and treatment of numerous renal and metabolic disorders, including renal failure, gout, leukemia, psoriasis, starvation/ other wasting conditions, and in-patients receiving cytotoxic drugs.

Run Day: Daily
Reporting Day: Same day

Urinary Protein Creatinine Ratio (UPCR), Spot Urine

Test Code: 6140 CPT Code: Use individual CPTCodes
Specimen Type: Spot urine
Sample Volume: 3.0 mL
Transport Condition: Room temperature
Specimen Rejection Criteria: Not Applicable
Methodology: Electrophoresis
Special Requirements: No special precautions needed
Clinical Significance:

Persistently increased protein excretion is usually a marker of kidney damage. Quantifying protein in urine is commonly used in the diagnosis of kidney diseases, detection of treatment effects and evaluation of prognosis.
Urinary protein creatinine ratio in spot urine (UPCR) can be used as an alternative to urine protein excretion in 24 hrs collections. UPCR in first morning urine samples is better than that in random specimens, especially for outpatients.

Run Day: Daily
Reporting Day: Same day

Urine Analysis, Routine, with Occult Blood, Qualitative

Test Code: 1276 CPT Code: 81005
Specimen Type: Urine in sterile leak proof container
Sample Volume: 10 mL
Transport Condition: Room temperature
Specimen Rejection Criteria: NA
Methodology: Microscopy
Special Requirements: No special precautions needed
Clinical Significance:

Urinalysis is important in accessing the chemical constituents in the urine and its relationship to various disease conditions.Microscopic examination helps to detect the presence of abnormal urine cells and formed elements.

Run Day: Daily
Reporting Day: Same day
