Neisseria Gonorrhoeae DNA Detection, PCR
| Test Code: 22053 |
CPT Code: 87591 |
| Specimen Type: Genital/ rectal swabs/ urine |
| Sample Volume: Swab: 1, culture/ urine: 5 mL |
| Transport Condition: Refrigerated condition/ room temperature |
| Specimen Rejection Criteria: Nil |
| Methodology: Multiplex-Real Time PCR |
| Special Requirements: Specimen source and clinical history required |
| Clinical Significance: Gonorrhea, a very common sexually transmitted disease, is caused by the bacterium Neisseria gonorrhoeae. The organism causes genitourinary infections in women and men and may be associated with dysuria and vaginal, urethral, or rectal discharge. Nucleic acid amplification testing (NAAT) like Multiplex-Real Time PCR provides not only rapidity, but also superior sensitivityand specificity as compared to routine culture techniques.

| Run Day: Sat, Tue |
| Reporting Day: 3rd day |
Nicotine Metabolite, Urine
| Test Code: 13002 |
CPT Code: 80323 |
| Specimen Type: Urine |
| Sample Volume: 1 mL |
| Transport Condition: Refrigerated condition |
| Specimen Rejection Criteria: Nil |
| Methodology: Flow Chromatographic Immunoassay |
| Special Requirements: Collect a random urine specimen.No preservative. |
| Clinical Significance: Tobacco use is the leading cause of death worldwide. Nicotine stimulates dopamine release and increases dopamine concentration in the nucleus accumbens,
a mechanism that is thought to be the basis for addiction for drugs of abuse. This assay is used for monitoring tobacco use and also for monitoring patients on nicotine-replacement therapy.

NIPT (Non Invasive Prenatal Test), for Trisomies 21, 18, 13
| Test Code: 13737 |
CPT Code: 81507 |
| Specimen Type: |
| Sample Volume: 10 mL |
| Transport Condition: Room temperature/ Refrigerated condition |
| Specimen Rejection Criteria: Sample collected in any other tube |
| Methodology: DNA sequencing by NGS paired-end sequencing technology |
| Special Requirements: The following information is required on the TRF supplied by the laboratory: Reason for referral, maternal age, number of fetuses, gestation age (weeks and days), method of determining gestational age, maternal height, maternal weight, whether IVF pregnancy, etc. |
| Clinical Significance: Chromosomal aneuploidy is the leading genetic cause of miscarriage and congenital birth defects. This cell-free DNA prenatal screening enables de-tection of common chromosomal abnormalities, specifically aneuploidy including Down syndrome (trisomy 21), Patau syndrome (trisomy 13), and Edward syndrome (trisomy 18), without the risk of pregnancy loss associated with invasive prenatal procedures.

NMDA Receptor Encephalitis Antibodies, IgG, Serum/ CSF
| Test Code: 22045 |
CPT Code: 86256 |
| Specimen Type: Serum (yellow-top tube)/ CSF |
| Sample Volume: Serum: 3.0mL (1.0 mL
- min), CSF:
2.0 mL |
| Transport Condition: Refrigerated condition |
| Specimen Rejection Criteria: Gross hemolysis |
| Methodology: Immunofluorescent Assay |
| Special Requirements: Include relevant clinical information, name & phone number of ordering clinician. |
| Clinical Significance: Anti-NMDA receptor encephalitis, also known as NMDA receptor antibody encephalitis, causes acute brain inflammation that is potentially lethal but has a high probability for recovery with treatment. It is caused by an immune system attack, primarily targeting the NR1 subunit of the NMDA receptor (N-methyl D-aspartate receptor). This assay aids in the diagnosis of anti-NMDA receptor encephalitis.

Non-invasive Prenatal Genetic Testing for Fetal Chromosomal Aneuploidies (NIFTY)
| Test Code: 9465 |
CPT Code: Use individual CPTCodes |
| Specimen Type: 3 mL blood in EDTA (lavender-top) tube; 5 mL in tube provided in kit |
| Sample Volume: Peripheral blood: 3mL & 5 mL |
| Transport Condition: Refrigerated condition |
| Specimen Rejection Criteria: Gross hemolysis |
| Methodology: NIFTY |
| Special Requirements: Clinical history in the predefined format along with patient consent is mandatory |
| Clinical Significance: Refer report for details
|
| Run Day: Daily |
| Reporting Day: 14th day |
NT Pro BNP
| Test Code: 5789 |
CPT Code: 83880 |
| Specimen Type: Heparinized venous whole blood in a green- top (heparin) tube |
| Sample Volume: 3.0 mL (1.0mL - min) |
| Transport Condition: Room temperature |
| Specimen Rejection Criteria: Serum collected in a yellow-top tube, Plasma |
| Methodology: POCT |
| Special Requirements: No special precautions needed |
| Clinical Significance: Widely used clinical application of NT-proBNP testing is for the emergent diagnosis of CHF in patients presenting with acute dyspnea. Nevertheless, elevated NPs levels can be found in many conditions involving left ventricular dysfunction/ hypertrophy, right ventricular dysfunction secondary to pulmonary diseases, cardiac inflammatory/ infectious diseases, endocrine diseases
and high output status without decreased LV ejection fraction. Even in the absence of significant volume overload or LV dysfunction, markedly elevated proBNP levels can be found in patients with multiple comorbidities.
