Insurance Blood Tests: What Do They Actually Reveal?

what do insurance blood tests check for

Blood tests are a common part of the life insurance application process. They are used by insurers to assess an applicant's health and, in turn, their eligibility for coverage and pricing. Blood tests can check for a range of factors, including cholesterol levels, blood sugar, liver and kidney function, and the presence of drugs or nicotine. While blood tests are a standard requirement, they are not mandatory for all policies, and some insurers may offer coverage without them.

Characteristics Values
Purpose To determine eligibility and pricing for certain types of life insurance policies
Factors Cholesterol levels, blood sugar, A1c, liver and kidney function, presence of drugs or nicotine
Results If serious conditions or risk factors are detected, insurers may deny coverage or adjust premiums
Preparation Avoid alcohol, caffeine, and tobacco for 24 hours before the test; make lifestyle changes in advance to improve results
Process Verification of identity, measurements, urine and blood samples, blood pressure and pulse checks, EKG (if applicable)
Time Typically 15-30 minutes for the exam, with results taking a few days to a few weeks

Blood sugar levels

Blood glucose tests can be done through a finger prick or a blood draw from a vein. The most common type of blood sugar monitoring involves using a glucose meter and test strips, which is often referred to as a "finger stick check". For this test, a small needle called a lancet is used to prick the fingertip and produce a blood drop. The blood is then placed against the test strip in the glucose meter, which displays the blood sugar level within seconds.

There are also continuous glucose monitors (CGM) that measure glucose levels 24 hours a day. CGMs use the data to form a graph that shows how blood sugar levels change over time. People with diabetes may need to check their blood sugar levels several times a day using the finger stick method.

The fasting plasma glucose (FPG) test measures blood glucose levels at a single point in time, usually after a person has fasted for at least eight hours. The oral glucose tolerance test (OGTT) is another method used to diagnose gestational diabetes in pregnant women. For this test, blood samples are taken before and after the patient consumes a sugary drink. The A1C test, also known as the hemoglobin A1C, HbA1C, glycated hemoglobin, or glycosylated hemoglobin test, provides information about average blood glucose levels over the past three months.

Kidney function

There are several types of kidney function tests, including blood tests and urine tests. Blood tests can check kidney function by measuring the amount of creatinine in the blood. Creatinine is a waste product that comes from the digestion of protein in food and the normal breakdown of muscle tissue. Healthy kidneys remove creatinine from the blood, so if your kidneys are not working well, your creatinine level will increase. However, it is important to note that "normal" creatinine levels can vary depending on factors such as age, sex, and body size.

Another blood test that can be used to assess kidney function is the cystatin C test. Cystatin C is a protein filtered by the kidneys, and its levels can provide an estimate of kidney function. This test may be particularly useful if there are concerns about the reliability of creatinine-based results.

Urine tests can also be used to assess kidney function. One such test is the urine albumin-creatinine ratio (uACR) test, which measures the amount of albumin (a type of protein) and creatinine in the urine. Healthy kidneys keep albumin in the blood while filtering out creatinine into the urine, so there should be little to no albumin in the urine. A high uACR level can indicate albuminuria, which may be a sign of kidney disease even if your eGFR is in the normal range.

In certain situations, a more accurate measure of kidney function may be needed, and a measured glomerular filtration rate (mGFR) test may be ordered. This test directly measures how well the kidneys are removing waste products from the blood and can involve a 24-hour urine collection or multiple blood samples taken over several hours.

Overall, kidney function tests are important tools that can help detect kidney issues early on and guide treatment decisions.

Presence of drugs

Insurance companies have the right to require drug tests for health and life insurance policies, but such requests are uncommon. Testing mostly happens in professions where the health and safety of others is a primary concern, such as pilots and heavy equipment operators.

If an insurance company does choose to test for drugs, they will typically use a urine sample, which is the most common method of drug testing. However, blood tests can also be used to detect the presence and level of drugs in the body. Blood tests can detect prescription drugs, including benzodiazepines, barbiturates, tetrahydrocannabinol (THC), and opiates such as codeine and oxycodone. They can also detect illegal drugs such as methamphetamine and cannabis, although urine tests are more commonly used for a comprehensive analysis of drug use.

The results of drug tests are generally kept confidential and are protected by doctor-patient confidentiality. However, there may be some situations in which a doctor must share a patient's medical records, such as when a court order is involved.

If an individual fails a drug test, it can result in the loss of employment or an increase in insurance premiums. Insurance companies may also refuse to provide coverage or demand higher premiums if they see signs of drug abuse. Life insurance companies, in particular, may reject a policy application if illegal drug use is detected.

It is important to note that the presence of drugs in an individual's system does not always indicate drug abuse. Prescription medications, over-the-counter drugs, or even certain foods can lead to positive test results. Therefore, it is crucial to disclose any medications or supplements being taken to the testing professional to ensure accurate interpretation of the test results.

Liver function

The tests measure the levels of various substances, including albumin, total protein, ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), GGT (gamma-glutamyl transferase), and bilirubin. Abnormal levels of these substances can indicate different diseases or conditions affecting the liver. For example, increased levels of ALP and GGT can suggest obstructive or cholestatic liver disease, where the flow of bile from the liver is blocked.

Cholesterol levels

High cholesterol levels can lead to serious health issues, including heart disease, heart attack, and stroke. It is a major risk factor for heart disease and often has no symptoms, so many people are unaware they have it. This is why it is important to get your cholesterol numbers checked regularly.

Cholesterol is a waxy substance that is essential for producing certain hormones and building the outer membrane of every cell. However, too much cholesterol can build up in your blood vessels and cause serious health issues. This is known as hyperlipidemia.

A cholesterol test, also called a lipid panel or lipid profile, requires a blood draw. A healthcare provider will take a sample of blood from a vein in your arm and send it to a lab for analysis. You will likely need to fast for 8 to 12 hours before the test.

The test measures your levels of:

  • Low-density lipoprotein (LDL) or "bad" cholesterol. High levels of LDL can lead to plaque buildup in your arteries, increasing the risk of heart disease and stroke.
  • High-density lipoprotein (HDL) or "good" cholesterol. HDL helps to remove LDL cholesterol from your blood and high levels can lower your risk of heart disease and stroke.
  • Triglycerides, a type of fat in the blood that the body uses for energy. High levels of triglycerides, along with low HDL or high LDL levels, can increase the risk of a heart attack and stroke.
  • Total cholesterol, which is the total amount of cholesterol in your blood based on your HDL, LDL, and triglyceride numbers.

The ideal cholesterol levels for most adults are:

  • HDL ("good" cholesterol): ideally above 60.
  • LDL ("bad" cholesterol): should be below 100.
  • Total cholesterol: should be below 200.

It is important to discuss your cholesterol test results with a healthcare provider to understand what they mean for your health and how to manage your cholesterol levels.
