On-Site Laboratory

Why do I need laboratory tests?

Laboratory tests are invaluable in primary care. They help determine what's causing any symptoms you have and monitor your health when you're recovering from a disease or living with a chronic condition.

Lab tests can isolate particular strains of viruses and bacteria so you receive the most effective treatment. They can also identify problems like micronutrient deficiencies, inflammation, and genetic disorders.

Premier NW Houston Medical Group has its own onsite laboratory where they carry out a range of tests.

What kinds of tests take place at the onsite laboratory?

Some of the many tests available at Premier NW Houston Medical Group's onsite laboratory include:

  • COVID-19 rapid antigen test
  • COVID-19 antibody tests
  • PCR (polymerase chain reaction) tests
  • Rapid strep test
  • Influenza A and B test
  • Blood glucose test
  • Cholesterol level measurement
  • Hemoglobin test
  • Rheumatoid factor test
  • Sexually transmitted disease (STD) tests

These onsite lab tests identify and help monitor chronic diseases as well as acute health problems.

What samples are used at the onsite laboratory?

Blood is the most common testing medium, with urine not far behind. Depending on your symptoms, you might need to have other substances sampled, such as:

  • Saliva
  • Sputum
  • Discharge fluids
  • Feces
  • Semen
  • Skin or soft tissue cells

Blood contains more information and a wider range of disease indicators than other substances. If your symptoms are ones that could have many potential causes, your provider at Premier NW Houston Medical Group orders a complete blood workup from their onsite laboratory.

How are samples taken for the onsite laboratory?

To take a blood sample, your provider draws the blood from your arm using a needle to carefully puncture a vein. The needle causes a momentary sting as it goes in, which many patients don't mind. If you have sensitivities or don't like needles, you can put a numbing cream on beforehand.

Waste products like urine and feces or sperm samples you need to collect yourself in the sterile container your provider gives you. Collecting cell or discharge samples involves your provider rubbing a cotton swab over the tissues.  

Having state-of-the-art onsite laboratory facilities is far more convenient for you, and also ensures you get your results promptly. The sooner your test results come back, the more quickly you can get the right treatment and start to feel better.
