Blood work can provide useful information when symptoms do not point to one obvious cause. A provider may use a blood test to look for signs of infection, anemia, blood sugar concerns, dehydration, or changes involving the kidneys, liver, or other parts of the body.
Urgent care can perform many common blood tests when laboratory testing is appropriate for a current health concern, physical exam, or monitoring need. Access Total Care’s Padre Island clinic specifically offers lab work, including blood work, urinalysis, and other diagnostic procedures. Its broader urgent care services include reference blood work such as complete blood counts, comprehensive metabolic panels, lipid tests, and prostate-specific antigen testing.
However, blood work is not one universal test. The appropriate test, preparation, and follow-up depend on why the testing is being performed. Understanding how the process works can help Corpus Christi patients arrive prepared and know what to expect after the sample is collected.
What Can Blood Work Help Evaluate?
Laboratory testing can serve several purposes. It may help a provider:
- Look for possible signs of infection
- Check red blood cells, white blood cells, and platelets
- Evaluate blood sugar levels
- Measure electrolytes and other substances in the blood
- Review certain markers related to kidney or liver function
- Check cholesterol and triglyceride levels
- Monitor a known health condition
- See how the body is responding to a medication or treatment
A blood test does not always provide a diagnosis by itself. Results are generally considered alongside a person’s symptoms, health history, medications, physical examination, and previous test results.
According to MedlinePlus, laboratory tests may be used to screen for health conditions, help make a diagnosis, guide treatment decisions, or monitor a condition over time. The same test may therefore be ordered for different reasons in different patients.
Which Blood Tests Does Access Total Care Offer?
Access Total Care’s urgent care page specifically identifies several forms of reference blood work:
- Complete blood count, or CBC: A CBC measures different types of blood cells. It may help identify findings associated with anemia, infection, inflammation, bleeding concerns, or certain other conditions.
- Comprehensive metabolic panel, or CMP: A CMP measures several substances, including glucose, electrolytes, proteins, and markers related to kidney and liver function.
- Lipid testing: Lipid tests measure cholesterol and triglycerides and may be used as part of a cardiovascular risk assessment.
- Prostate-specific antigen, or PSA, testing: A PSA test measures a substance produced by the prostate. Whether the test is appropriate depends on the patient’s age, history, symptoms, and discussion with a healthcare professional.
The Padre Island location also lists A1C testing. An A1C test estimates a person’s average blood sugar level over approximately the previous two to three months. Not every patient needs all of these tests. A provider can determine which tests are relevant to the concern being evaluated.
Can You Walk Into Urgent Care Just for Blood Work?
Patients may visit urgent care because of symptoms and have blood work ordered as part of the evaluation. For example, a provider may determine that testing would be useful after reviewing fatigue, dizziness, weakness, nausea, fever, or another concern.
Blood work may also be connected to a physical, health screening, or ongoing medical condition. In those cases, the clinic may need information about the specific test requested and who will be responsible for reviewing the results.
Patients who already have a laboratory order from another healthcare professional should contact the clinic before arriving. Some orders may require a particular laboratory, specimen process, or follow-up arrangement. Bringing a copy of the order can help prevent confusion about which tests are needed. Patients seeking long-term monitoring of a chronic condition may also benefit from establishing care through Access Total Care’s primary care services.
Do You Need To Fast Before Blood Work?
Some blood tests require fasting, while many do not. A CBC usually does not require special preparation unless other tests are being performed on the same sample. Some glucose, cholesterol, triglyceride, metabolic, or other tests may require a period without food. When fasting is required, the instructions should specify:
- How many hours to fast
- Whether plain water is allowed
- Whether morning testing is recommended
- Whether medications should be taken as usual
- Whether coffee, gum, smoking, or exercise should be avoided
Patients should not decide to fast based only on the general name of the test. Requirements can differ depending on the laboratory method and what the provider is trying to evaluate.
MedlinePlus advises patients to follow the preparation instructions provided for their specific test. Patients should not stop prescription medications unless a healthcare professional tells them to do so. If you were asked to fast but accidentally ate or drank something other than water, tell the clinic before the blood draw. The test may still be useful, or it may need to be rescheduled.
What Should You Bring to a Lab Visit?
Useful items and information may include:
- A photo ID
- Insurance or payment information
- Any laboratory order or employer paperwork
- A current list of prescription and nonprescription medications
- Information about vitamins and supplements
- Relevant previous test results
- A list of allergies
- The time you last ate or drank
- A short description of current symptoms and when they began
Tell the medical team if you have previously fainted during blood draws, have difficulty with blood collection, take a blood thinner, or have a condition that affects bleeding. Staff may be able to adjust your position or take additional precautions. Drinking an appropriate amount of water may make a blood draw easier unless you were given different instructions. Coffee, flavored water, juice, and other drinks may affect some fasting tests.
What Happens During the Blood Draw?
A healthcare professional usually collects blood from a vein in the arm. The skin is cleaned, a band is placed around the upper arm, and a small needle is inserted into the vein. One or more tubes may be collected depending on the tests ordered.
The actual collection often takes only a few minutes. Patients may feel a brief sting or pressure. Mild tenderness or bruising can occur afterward. After the needle is removed, pressure is placed over the site. Keep the bandage on for the amount of time recommended by the person collecting the sample. Tell the staff if you feel dizzy, weak, sweaty, or nauseated before standing up.
How Are Blood Test Results Interpreted?
Laboratory reports often show a result beside a reference range. A number outside that range does not automatically mean that a person has a disease. Age, medications, hydration, recent meals, exercise, illness, and other factors can affect results.
Reference ranges may also differ between laboratories. A result should be compared with the range printed on that specific report rather than a range found online. When monitoring a condition over time, the overall trend may be more informative than one isolated number. Depending on the findings, the next step may be:
- No additional testing
- A repeat test
- A follow-up visit
- Changes to medication or lifestyle
- Additional laboratory or imaging tests
- Referral to a primary care provider or specialist
- Emergency evaluation for a significantly concerning result
Patients should ask how and when results will be communicated. A result marked “high,” “low,” or “abnormal” should be interpreted by a healthcare professional who understands why the test was ordered.
When Is Urgent Care Not the Right Setting?
Urgent care is designed for health concerns that require timely attention but do not appear immediately life-threatening. Blood work may help evaluate many symptoms, but testing should not delay emergency care. Call 911 or seek emergency treatment for symptoms such as:
- Severe difficulty breathing
- New chest pain or pressure
- Signs of a stroke
- Fainting or inability to wake
- Severe confusion
- Uncontrolled bleeding
- A serious allergic reaction
- A major injury
- Rapidly worsening weakness or illness
An emergency department can provide continuous monitoring, advanced imaging, emergency medications, and other services that may be necessary for severe symptoms.
