Can a blood test detect opioids?
What is opioid testing? – Opioid testing looks for the presence of opioids in urine, blood, or saliva. Opioids are powerful drugs that are used to relieve pain. They are often prescribed to help treat serious injuries or illnesses. In addition to reducing pain, opioids can also increase feelings of pleasure and well-being.
Once an opioid dose wears off, it’s natural to want those feelings to return. So even using opioids as prescribed by a doctor can lead to dependence and addiction, The terms “opioids” and “opiates” are often used in the same way. An opiate is a type of opioid that comes naturally from the opium poppy plant.
Opiates include the medicines codeine and morphine, as well as the illegal drug heroin, Other opioids are synthetic (man-made) or part synthetic (part natural and part man-made). Both types are designed to produce effects similar to a naturally occurring opiate.
- Oxycodone (OxyContin®)
- Hydrocodone (Vicodin®)
- Fentanyl. Drug dealers sometimes add fentanyl to heroin. This combination of drugs is especially dangerous.
Opioids are often misused, leading to overdoses and death. In the United States, tens of thousands of people die every year from opioid overdoses, Opioid testing can help prevent or treat addiction before it becomes dangerous. Other names: opioid screening, opiate screening, opiate testing
What is the cutoff for opiates on a drug test?
(a) Initial drug testing, (1) HHS-certified laboratories shall apply the following cutoff levels for initial testing of specimens to determine whether they are negative or positive for the indicated drugs and drug metabolites, except as specified in paragraph (a)(2) of this section or the licensee or other entity has established more stringent cutoff levels: TABLE 1 TO PARAGRAPH (a)(1)— URINE, INITIAL TEST CUTOFF LEVELS FOR DRUGS AND DRUG METABOLITES
|Drugs or drug metabolites||Cutoff level|
|Opioids: Codeine/Morphine 1 Hydrocodone/Hydromorphone Oxycodone/Oxymorphone 6–acetylmorphine (6–AM)||2000 300 100 10|
|Amphetamines: 2 AMP/MAMP 3 MDMA 4 /MDA 5||500 500|
1 Morphine is the target analyte for codeine/morphine testing.2 Either a single initial test kit or multiple initial test kits may be used provided the single test kit detects each target analyte independently at the specified cutoff.3 Methamphetamine (MAMP) is the target analyte for amphetamine (AMP)/MAMP testing.4 Methylenedioxymethamphetamine.5 Methylenedioxyamphetamine.
|Drugs or drug metabolites||Cutoff level 1|
|Marijuana (THC) 2 3||4|
|Opioids: Codeine/Morphine Hydrocodone/Hydromorphone Oxycodone/Oxymorphone 6–acetylmorphine (6–AM)||30 30 30 4 3|
|Amphetamines: AMP/MAMP 4 MDMA/MDA 5||50 50|
1 For grouped analytes ( i.e., two or more analytes in the same drug class with the same initial test cutoff):
Immunoassay: The test must be calibrated with one analyte from the group identified as the target analyte. The cross reactivity of the immunoassay to the other analyte(s) within the group must be 80 percent or greater; if not, separate immunoassays must be used for the analytes within the group. Alternative technology: Either one analyte or all analytes from the group must be used for calibration, depending on the technology. At least one analyte within the group must have a concentration equal to or greater than the initial test cutoff or, alternatively, the sum of the analytes present.
2 An immunoassay must be calibrated with the target analyte, delta-9-tetrahydrocannabinol (THC).3 Alternate technology (THC and 6–AM): The confirmatory tests cutoff must be used for an alternate technology initial test that is specific for the target analyte ( i.e.
2 ng/mL for THC, 2 ng/mL for 6–AM).4 Amphetamine (AMP) and methamphetamine (MAMP).5 Methylenedioxymethamphetamine (MDMA) and methylenedioxyamphetamine (MDA). (2) HHS-certified laboratories shall conduct special analyses of specimens as follows: (i) If initial validity testing indicates that a specimen is dilute, or if a specimen is collected under direct observation for any of the conditions specified in § 26.115(a)(1) through (3) or (a)(5), the laboratory shall compare the immunoassay responses of the specimen to the cutoff calibrator in each drug class tested; (ii) If any immunoassay response is equal to or greater than 40 percent of the cutoff calibrator, the laboratory shall conduct confirmatory drug testing of the specimen to the LOQ for those drugs and/or drug metabolites; and (iii) The laboratory shall report the numerical values obtained from this special analysis to the MRO.
(b) Confirmatory drug testing, (1) A specimen that is identified as positive on an initial drug test must be subject to confirmatory testing for the class(es) of drugs for which the specimen initially tested positive. The HHScertified laboratory shall apply the confirmatory cutoff levels specified in this paragraph, except as permitted in paragraph (a)(2) of this section or the licensee or other entity has established more stringent cutoff levels.
|Drugs or drug metabolites||Cutoff level (ng/mL)|
|Marijuana metabolite 1||15|
|Cocaine metabolite 2||100|
|Opiates: Morphine Codeine Hydrocodone Hydromorphone Oxycodone Oxymorphone 6–acetylmorphine (6–AM)||2000 2000 100 100 100 100 10|
|Amphetamines: Amphetamine Methamphetamine 3 Methylenedioxymethamphetamine (MDMA) Methylenedioxyamphetamine (MDA)||250 250 250 250|
1 As delta-9-tetrahydrocannabinol-9-carboxylic acid (THCA).2 As benzoylecgonine.3 To be reported positive for methamphetamine, a specimen must also contain amphetamine at a concentration equal to or greater than 100 ng/mL. TABLE 4 TO PARAGRAPH (b)(1)— ORAL FLUID, CONFIRMATORY TEST CUTOFF LEVELS FOR DRUGS AND DRUG METABOLITES
|Drugs or drug metabolites||Cutoff level|
|Opiates: Codeine Morphine Hydrocodone Hydromorphone Oxycodone Oxymorphone 6–acetylmorphine (6–AM)||15 15 15 15 15 15 2|
|Amphetamines: Amphetamine Methamphetamine Methylenedioxymethamphetamine (MDMA) Methylenedioxyamphetamine (MDA)||25 25 25 25|
2) Each confirmatory drug test must provide a quantitative result. When the concentration of a drug or metabolite exceeds the linear range of the standard curve, the laboratory may record the result as “exceeds the linear range of the test” or as “equal to or greater than,” or may dilute an aliquot of the specimen to obtain an accurate quantitative result when the concentration is above the upper limit of the linear range.
Is opioid damage permanent?
Even in a short period of time, opioids can negatively affect the health of the brain. While an opioid has the ability to bind to the brain’s pleasure receptors & manage pain effectively, an opioid also attaches to non-pleasure receptors in the brain & spinal cord, which masks pain in the body.
- Opioids target the brain’s reward system and flood the circuit with dopamine, a neurotransmitter that regulates movement, emotion, and feelings of pleasure.
- Since opioids target the brain’s pleasure receptors, some people experience euphoria.
- Studies also show that psychological addiction can take place in just 3 days.
Over time, the brain adjusts its functioning to accommodate the intake of opioids and loses its ability to function normally without the opioids being present. Opioid withdraws consists of various symptoms that can cause intense psychological & physical distress in a person’s body. The pain of the withdraw can be intensely painful but being opioid-free is worth it! #DidYouKnow? Prolonged use of opioids can lead to permanent damage to a person’s organs, including the kidneys and liver? But there’s something far worse – Even a first time user can experience respiratory arrest or respiratory failure and/or sudden cardiac arrest.
Blood: Heroin or crushed-pill injections can cause veins to collapse & shared needles increase the risk of contracting HIV; Brain: Heavy opioid use can cause sedation, depression; Digestive System: Slowing of the digestive system can result in constipation, nausea & at heightened risk for more serious conditions, such as small bowel obstruction, perforation & resultant peritonitis; Heart: Heart lining can become infected due to contamination from opioid use; Immune System: Vulnerability & infection can occur due to reduced immune response; Liver: Shared infected needles can cause hepatitis; Lungs: Ensuring respiratory depression can lead to slowed breathing, which is potentially fatal; Respiratory arrest can deprive the brain and body tissues of oxygen & result in debilitating organ system injury, which can easily prove fatal; Nervous System: Chronic opioid abuse can create a greater sensitivity to pain called Opioid Hyperalgesia ; Skeletal System: Individuals who abuse opioids are more likely to suffer from fractures & broken bones because they’re at higher risk of bone thinning & loss due to regrowth impairment. A study published in the Journal of American Geriatrics Society notes that 3 percent of patients suffered a fracture in the first 14 days of using short-acting opioids versus 0.4 percent of people who used ibuprofen.

How are opiates cleared?
R enal I mpairment – The incidence of renal impairment increases significantly with age, such that the glomerular filtration rate decreases by an average of 0.75 to 0.9 mL/min annually beginning at age 30 to 40 years.102, 103 At this rate, a person aged 80 years will have approximately two-thirds of the renal function expected in a person aged 20 or 30 years.102 – 104 Because most opioids are eliminated primarily in urine, dose adjustments are required in patients with renal impairment.10, 11, 13, 16 – 18, 43 However, the effects of renal impairment on opioid clearance are neither uniform nor clear-cut.
For example, morphine clearance decreases only modestly in patients with renal impairment, but clearance of its M6G and M3G metabolites decreases dramatically.105 – 107 Accumulation of morphine glucuronides in patients with renal impairment has been associated with serious adverse effects, including respiratory depression, sedation, nausea, and vomiting.73, 74, 108 Similarly, patients with chronic renal failure who receive 24 mg/d of hydromorphone may have a 4-fold increase in the molar ratio of hydromorphone-3-glucuronide to hydromorphone.109 Conversely, in patients treated with oxycodone, renal impairment increases concentrations of oxycodone and noroxycodone by approximately 50% and 20%, respectively.11 Although renal impairment affects oxycodone more than morphine, there is no critical accumulation of an active metabolite that produces adverse events.11 Thus, selecting an opioid in patients with renal impairment requires an understanding not only of the anticipated changes in concentrations of the opioid and its metabolites but also of the differential effects of parent compounds and metabolites when they accumulate.
As in liver disease, methadone and fentanyl may be less affected by renal impairment than other opioids. Methadone does not seem to be removed by dialysis 110 ; in anuric patients, methadone excretion in the feces may be enhanced with limited accumulation in plasma.111 However, for patients with stage 5 chronic kidney disease, the prudent approach remains to begin with very low doses, monitor carefully, and titrate upward slowly.
What is a low opiate cutoff?
The cutoff levels listed in Table 1 are consistent with testing for employment but not necessarily for aberrant behavior in patients receiving long-term opioid therapy. These cutoffs lower the risk of false positives and provide better accuracy with clinical monitoring.
For example, a level of 2,000 ng/mL is listed for both test types in Table 4, but for clinical testing, the IA cutoff is 3,000 ng/mL, and gas chromatography/mass spectrometry (GC-MS) can detect even trace amounts of opioid and their metabolites. Clinicians must be familiar with the available tests at their institution.
Most commonly when monitoring patients that are prescribed pain medications, the IA panel includes the Federal Five plus benzodiazepines, barbiturates, and often methadone as well.
What is opioid score?
This tool should be administered to patients upon an initial visit prior to beginning opioid therapy for pain management. A score of 3 or lower indicates low risk for future opioid abuse, a score of 4 to 7 indicates moderate risk for opioid abuse, and a score of 8 or higher indicates a high risk for opioid abuse.
What do opioids do to your body long-term?
What are some possible effects of prescription opioids on the brain and body? – In the short term, opioids can relieve pain and make people feel relaxed and happy. However, opioids can also have harmful effects, including:
- slowed breathing
Opioid misuse can cause slowed breathing, which can cause hypoxia, a condition that results when too little oxygen reaches the brain. Hypoxia can have short- and long-term psychological and neurological effects, including coma, permanent brain damage, or death. Researchers are also investigating the long-term effects of opioid addiction on the brain, including whether damage can be reversed.
Do opiates have long-term effects?
Studies show that long-term opioid treatment increases the risk of fractures, infections, cardiovascular complications, sleep-disordered breathing, bowel dysfunction, overdose, and mortality.
