Ordering Recommendation:  

Preferred test in the workup of multiple sclerosis. Detect unique IgG oligoclonal bands in cerebrospinal fluid (CSF) in conjunction with a matched serum specimen. Calculate CSF IgG index.

8.
Ordering Recommendation:  

Use for assessment of multiple sclerosis. Detect unique IgG oligoclonal bands in cerebrospinal fluid (CSF) in conjunction with a matched serum specimen. Preferred test is Oligoclonal Band Profile (0080440).

9.
Ordering Recommendation:  

Useful for general screening in contexts of compliance and/or abuse. For follow-up testing of a presumptive result, confirmatory testing by mass spectrometry is recommended. For automatic reflex testing on all presumptive positives, Opiates, Urine Screen with Reflex to Quantitation (2005093) is recommended.

10.
Ordering Recommendation:  

Monitor patient adherence.

11.
Ordering Recommendation:  

Useful for general screening in contexts of compliance and/or abuse. A screen with reflex testing is the preferred method for ruling out opiate exposure. For follow-up testing of a presumptive result, Opiates, Urine, Quantitative (0090364) is preferred.

12.
Ordering Recommendation:  

Preferred test to follow-up presumptive results. For general screening, Opiates, Urine Screen with Reflex to Quantitation (2005093) is preferred.

13.
Ordering Recommendation:  

Pretherapeutic identification of individuals who may require higher or lower doses of opioid drugs to achieve adequate pain control or have a better response to naltrexone for the treatment of alcohol and/or opioid dependency.

14.
Ordering Recommendation:  

For routine biochemical screening for inherited disorders of metabolism, refer to Organic Acids, Urine (0098389).

16.
Ordering Recommendation:  

Reference method for identification of most bacterial species.

17.
Ordering Recommendation:  

Acceptable initial genetic test to confirm OTC deficiency, following suggestive clinical and laboratory findings. To diagnose or rule out OTC deficiency, refer to Amino Acids Quantitative by LC-MS/MS, Plasma (2009389), Organic Acids, Urine (0098389), and Orotic Acid, Urine (3000704).

25.
Ordering Recommendation:  

Detect extraintestinal parasites from other body fluids. To rule out Naegleria and other free living amoeba, consider ordering Acanthamoeba and Naegleria Culture (0060245) or Amoeba Calcofluor Stain (0060250). For CSF specimens, consider Acanthamoeba and Naegleria Culture and Stain, CSF (3000878).

26.
Ordering Recommendation:  

If parasite infection is suspected as cause of persistent diarrhea (> 14 days), specific pathogen testing is recommended (refer to Gastrointestinal Parasite Panel by PCR (2011150); Giardia Antigen by EIA (0060048); Entamoeba histolytica Antigen, EIA (0058001); or Cryptosporidium Antigen by EIA (0060045)). Do not order for patients who develop diarrhea during a prolonged hospitalization.
