These critical reporting limits have been defined specifically for a community laboratory environment and are based on published literature as well as laboratory experience.  \nLaboratories are obligated to communicate laboratory critical results. The ordering Health Care Provider has the professional responsibility to receive critical laboratory results. The Health Care Provider must provide the laboratory with contact information , which allows direct telephone communication of critical results to the HCP (or delegate providing coverage during absences) both during and after office hours. Health Care Providers can contact LifeLabs at 604-431-7206 or toll free 1-800-431-7206 to provide contact information or to update existing contact information.  \nLaboratory test results defined as critical are communicated as soon as they are available to the ordering physician 24 hours a day.  \nRecurrent Critical Values  \nThere may be situations when a markedly abnormal result is not unexpected. Certain critical values may be frequently expected in certain types of specialist practice. Under these circumstances an exception to the critical result calling protocol may be made; subject to approval by the LifeLabs Medical Director. The HCP must complete the Doctors Special Handling Request Form. Contact LifeLabs at 604-431-7206 or toll free 1-800-431-7206 for more information.  \nReporting Exceptions: Microbiology  \nWhen a preliminary report which is considered critical is successfully communicated by the laboratory, further preliminary and the final microbiology report will not be communicated as a second critical value. It is the responsibility of the ordering Health Care Provider to obtain additional information from the final report to confirm the appropriateness of treatment.  \nCritical Values are updated periodically and may change without notification. Critical values on the patient report are deemed to be correct.  \n\n| Chemistry and Urinalysis Routine |  |  |  |  |\n| --- | --- | --- | --- | --- |\n| Test | Low Critical | High Critical |  | Units |\n| AM Cortisol | \u003C100 if \u003C1 y |  |  | nmol/L |\n| Bilirubin |  | >260 if \u003C4 d\u003Cbr>>290 if ≥4 d and ≤28 d |  | µmol/L |\n| Calcium, Total | \u003C1.50 | >3.25 |  | mmol/L |\n| Calcium, Ionized | \u003C0.80 | >1.60 |  | mmol/L |\n| CO2 | \u003C10 | >40 |  | mmol/L |\n| Glucose | \u003C2.5 | >11 .1\u003Cbr>>30.0 | if \u003C17 y\u003Cbr>if ≥17 y | mmol/L |\n| Lactate |  | >4.00 |  | mmol/L |\n| Magnesium | \u003C0.3 | >3.0 |  | mmol/L |\n| Phosphate | \u003C0.32 |  |  | mmol/L |\n| Potassium | \u003C2.8 | >6.5\u003Cbr>>6.2 | if \u003C3 m\u003Cbr>if ≥3 m | mmol/L |\n| Sodium | \u003C120 | >160 |  | mmol/L |\n| Troponin |  | >50.0 |  | ng/L |\n| TSH |  | >10 if \u003C1 y |  | mU/L |\n| Urinalysis Glucose and Ketones |  | Glucose ≥28\u003Cbr>Ketones ≥2 | if ≤29 y | mmol/L |\n\n\n| Chemistry Therapeutic Drug |  |  |  |  |\n| --- | --- | --- | --- | --- |\n| Test | Low Critical | High Critical |  | Units |\n| Carbamazepine |  | >65 |  | µmol/L |\n| Digoxin |  | >3.5 |  | nmol/L |\n| Lithium |  | >2.0\u003Cbr>>1.0 | if \u003C66 y\u003Cbr>if ≥66 y | mmol/L |\n| Phenobarbital |  | >260 |  | µmol/L |\n| Phenytoin |  | > 120 |  | µmol/L |\n| Theophylline |  | >110 |  | µmol/L |\n| Valproic Acid |  | >1000 |  | µmol/L |\n\n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n>>>  \n\n| Hematology and Coagulation |  |  |  |\n| --- | --- | --- | --- |\n| Test | Low Critical | High Critical | Units |\n| Hemoglobin | \u003C80 if 1d – 29 d | >250 if 1d – 29 d | g/L |\n|  | \u003C60 if >30 d |  |  |\n| Platelet count | \u003C20 |  | 109/L |\n| Neutrophils | \u003C0.5 | >100.0 | 109/L |\n| Lymphocytes |  | >250.0 | 109/L |\n|  |  |  |  |\n| PT (INR) |  | >6.0 |  |\n| PTT |  | > 100 | s","cbCaiqZKmfi6rheL","https://ap.wps.com/l/cbCaiqZKmfi6rheL","pdf",471911,"English","# Critical value definition and purpose\n## Communication obligations and contact process\n## Recurrent critical values and handling requests\n## Reporting exceptions for microbiology\n## Periodic updates and correctness on patient reports\n# Critical value tables\n## Chemistry and Urinalysis Routine\n## Chemistry Therapeutic Drug\n## Hematology and Coagulation\n## Microbiology: results phoned (alphabetical order)\n# References","[{\"question\":\"What is considered a critical laboratory value and what should happen next?\",\"answer\":\"A critical value indicates a patient may be in a life-threatening condition requiring immediate medical action.
