Why the Paramedical Lab Panel Matters
The blood and urine samples collected during your paramedical exam are the single largest factor in placing you into an underwriting rate class. A licensed examiner draws blood and collects a urine sample, ships the specimens to a contracted lab (ExamOne, APPS, or Superior Mobile Medics are the largest), and results are typically transmitted to the insurer's underwriting team within 24 to 72 hours of arrival. The lab is not just a rubber stamp. Studies of scored life insurance lab data show that mortality risk climbs in a nearly linear pattern from the healthiest quintile to the worst, which is why insurers weigh these numbers so heavily against your application answers.

The Standard Blood Panel: Marker by Marker
Every major US life insurer runs a similar core panel on the blood specimen. Here is what each test measures and the typical threshold for top rate classes.
Lipid profile (cholesterol)
The lipid panel reports total cholesterol, HDL ("good"), LDL ("bad"), triglycerides, and the cholesterol/HDL ratio. Underwriters care most about the ratio because it correlates most strongly with cardiovascular mortality. For Preferred Plus consideration, most carriers want total cholesterol under 300 mg/dL and a cholesterol/HDL ratio of 4.5 or lower. Triglycerides above 400 mg/dL will typically drop you at least one rate class on their own.
Blood glucose and A1c
Fasting glucose captures a snapshot of your blood sugar the morning of the draw, while Hemoglobin A1c reflects your average blood sugar over the previous 90 days. A1c is far more reliable and cannot be gamed by a one-day fast. A1c under 5.7% is normal, 5.7 to 6.4% is pre-diabetic, and 6.5% or above meets the diabetic threshold. Well-controlled diabetes with an A1c under 7.0% is often still insurable at Standard rates.
Liver enzymes
AST, ALT, and GGT are the three enzymes screened. Elevations can indicate fatty liver, alcohol overuse, hepatitis, medication side effects, or muscle breakdown from recent intense exercise. GGT specifically is sensitive to alcohol consumption, which is why one of the strongest prep tips is avoiding drinking for at least 48 to 72 hours before your exam.
Kidney function
The panel checks creatinine, BUN (blood urea nitrogen), and calculates eGFR (estimated glomerular filtration rate). Urine is also tested for protein and microalbumin, both early indicators of kidney disease. An eGFR above 90 is ideal; anything below 60 sustained over three months meets the definition of chronic kidney disease and will usually trigger a Table rating or decline.
PSA (men age 50+)
Men age 50 and older, and sometimes men 45+ with a family history of prostate cancer, receive a prostate-specific antigen (PSA) test. A PSA under 4.0 ng/mL is generally considered normal for insurance purposes. Elevated PSA rarely causes an outright decline but often triggers a request for an Attending Physician Statement (APS) from your urologist.
Complete blood count and protein markers
The CBC counts red cells, white cells, and platelets, flagging anemia, infection, or blood disorders. Total protein, albumin, and globulin help assess overall nutritional status, chronic inflammation, and liver synthetic function.
What the Urine Test Actually Detects
The urine cup does far more work than most applicants realize. Beyond confirming the sample belongs to you (via creatinine concentration and temperature), it screens for a wide range of substances and conditions.
| Marker Tested | What It Detects | Impact on Rate |
|---|---|---|
| Glucose in urine | Undiagnosed or poorly controlled diabetes | Standard to Table B+ |
| Protein/microalbumin | Early kidney disease | Standard to Table |
| Blood in urine | Kidney stones, infection, tumor | APS request, possible postpone |
| Cotinine | Nicotine use (any source) | Smoker rates (2-3x premium) |
| Cocaine metabolites | Recreational cocaine use | Usually decline |
| THC-COOH | Marijuana use | Rates vary by carrier |
| Amphetamines, opiates | Illicit or undisclosed use | Decline or heavy rating |
| HIV antibodies | HIV infection | Rating, sometimes decline |
| Hepatitis B/C surface antigens | Active or chronic hepatitis | Rating or postpone |
Illegal drug detection in the urine screen almost always results in a declination for a traditional policy. Undisclosed prescription medications, especially controlled substances like benzodiazepines, opioids, or stimulants that were not listed on your application, can be treated as material misrepresentation and cause the insurer to withdraw the offer.
Cotinine, Nicotine, and Marijuana: The Details That Trip Up Applicants
Marijuana is treated more leniently than it was five years ago. Roughly half of the major US life insurers will now offer non-smoker rates to occasional marijuana users, though heavy daily use often still triggers a smoker classification or higher premium. THC metabolites can be detected in urine for 3 to 5 days after occasional use and 30+ days for chronic daily users. For a deeper look at how tobacco and nicotine surcharges work and how to get reclassified after quitting, see our guide on life insurance for smokers.
How to Prepare: A Timeline That Actually Works
You cannot fake a good exam, but you can absolutely avoid unnecessarily bad numbers. Most poor results in otherwise healthy applicants come from dehydration, a late-night meal, a hard workout, or a couple of drinks the evening before.
7 days out
- Cut back on saturated fat, salt, and sugar
- Increase water intake to keep urine light yellow
- Skip alcohol if possible
- Sleep 7 to 8 hours nightly (chronic sleep loss raises blood pressure)
48 to 72 hours out
- No intense workouts. Heavy lifting or long runs elevate ALT, AST, and creatinine
- No alcohol. GGT and liver enzymes can spike for 2 to 3 days
- Continue drinking water steadily
The night before
- Begin your fast (aim for 8 to 12 hours)
- Water is fine and encouraged; nothing with calories
- Eat a light, low-fat dinner
- Sleep well
Morning of the exam
- Drink a full glass of water an hour before
- No coffee, tea, energy drinks, or nicotine
- No exercise beyond a light walk
- Have your medication list, doctor contacts, and ID ready
Turnaround Times and What Happens After
Most specimens reach the lab within 24 hours of the draw and analytes are processed within another 24 to 48 hours. Underwriting then reviews the full file, including your MIB report, MVR, prescription history, and any APS requests. The full decision typically arrives 3 to 6 weeks after your exam.
If HIV, hepatitis B, or hepatitis C is detected, most reputable insurers handle disclosure through your primary physician rather than by mail, and they do not automatically decline. Well-controlled HIV with an undetectable viral load, for example, is now insurable at several major carriers including Prudential, John Hancock, and MassMutual.
What Abnormal Results Mean for Your Rate Class
Rate classes translate directly into premium dollars. The table below shows how common abnormal findings typically shift an applicant's classification. Actual outcomes depend on severity, control, and combinations with other risks. For a full breakdown of each tier, review our guide on life insurance health classifications.
| Finding | Typical Rate Class Impact |
|---|---|
| Total cholesterol 240-300, ratio 4.5-6 | Preferred Plus → Preferred or Standard |
| A1c 5.7-6.4% (pre-diabetes) | Preferred → Standard |
| A1c 6.5-7.5%, well controlled | Standard, occasionally Table B |
| Mild ALT/AST elevation, isolated | Additional labs, then Standard likely |
| eGFR 60-89 with proteinuria | Standard to Table B |
| Cotinine positive | Automatic smoker rates (2-3x) |
| Cocaine or opiate positive | Decline |
| Undisclosed prescription meds | Rate adjustment or withdrawal |
If you know your health is borderline, it is often worth exploring options that skip the paramedical entirely. Our overview of the life insurance medical exam process covers accelerated underwriting programs and no-exam alternatives. Applicants with existing hypertension should also review our guide on life insurance with high blood pressure since blood pressure readings taken at the exam interact directly with your lab results.
Frequently Asked Questions
Can the life insurance blood test detect STDs?
The standard panel specifically screens for HIV and hepatitis B and C. It does not routinely test for other sexually transmitted infections like syphilis, gonorrhea, chlamydia, or herpes. A positive HIV or hepatitis result does not automatically disqualify you today, but it will typically move you into a rated (higher premium) class or trigger further underwriting review with your treating physician.
Do I really need to fast, and for how long?
Yes, if the insurer or paramedical company instructs you to. Most carriers ask for an 8 to 12 hour fast to get accurate fasting glucose and triglyceride readings. Water is not only allowed, it is encouraged because dehydration can artificially elevate creatinine and make the blood draw harder. Scheduling your exam for early morning is the simplest way to complete the fast overnight.
How long does marijuana stay detectable in the urine test?
For occasional users (a few times a month), THC metabolites are typically detectable for 3 to 5 days. For daily heavy users, THC-COOH can remain in urine for 30 days or more. Blood detection is shorter, usually 1 to 3 days for occasional use and up to 7 days for chronic users. If you use marijuana regularly, disclose it on the application rather than hoping it clears.
Will the insurer see prescription drugs I did not disclose?
Almost certainly. Beyond the urine screen, insurers pull your prescription history from Milliman IntelliScript or ScriptCheck, which report virtually every filled prescription in the US over the past 5 to 7 years. If your labs show drug metabolites or your prescription history contradicts your application, most carriers treat it as material misrepresentation, which can void the offer or, if discovered later, the policy itself.
Can I retake the blood test if my results come back bad?
Sometimes. If a specific value looks abnormal because of a temporary cause (recent illness, intense workout, a medication that was recently discontinued), underwriters may allow a retest 4 to 12 weeks later. For chronic issues like elevated A1c or persistent kidney markers, retesting will not help unless you have made real lifestyle or treatment changes in between. Ask your agent about a "reconsideration" request before accepting a downgraded offer.
