A complete blood count (CBC) is a common blood test that measures the different cells in your blood, including red blood cells, white blood cells, and platelets. Doctors order it to check your overall health and to help detect, diagnose, or monitor many conditions, such as infections, anemia, dehydration, and other blood disorders.
The 1,4-dichlorobenzene blood test measures the concentration of 1,4-dichlorobenzene in your serum (the liquid part of your blood). This chemical is commonly used in household products such as toilet bowl fresheners, mothballs, and air fresheners. The test helps determine if you have been exposed to elevated levels of this potentially harmful substance.
A health care professional will clean the skin on your arm, wrap a band around your upper arm, and draw a small sample of blood from a vein using a thin needle. The sample is sent to a laboratory, where instruments measure the number, size, and types of your blood cells. The draw usually takes only a few minutes and may cause a brief sting or slight bruising.
A healthcare professional will draw a blood sample from a vein in your arm. The sample is then sent to a laboratory where it is analyzed using specialized equipment to measure the amount of 1,4-dichlorobenzene present. No special preparation is typically required, but you should inform your doctor about any medications or supplements you are taking.
Your results show whether your red blood cells, white blood cells, and platelets fall within normal ranges. Values that are too high or too low may suggest conditions such as anemia, infection, inflammation, clotting or bleeding problems, or certain blood disorders. Many factors can affect the numbers, so your doctor will interpret them along with your symptoms, medical history, and other test results.
Results are typically reported as a concentration (mass/volume). Your healthcare provider will interpret the results based on reference ranges and your specific situation. Elevated levels may indicate recent exposure to 1,4-dichlorobenzene, which can occur through inhalation, skin contact, or ingestion. The test helps assess occupational exposure or investigate symptoms potentially related to chemical exposure.
Reference range
No established clinical reference range for serum 1,4-dichlorobenzene; results reported as detected/not detected or quantitative value compared to exposure limitsN/A
No specific fasting required; avoid exposure to products containing 1,4-dichlorobenzene (mothballs, air fresheners, pesticides) for 24-48 hours prior to collection if possible; document occupational and environmental exposure history
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
1,4-dichlorobenzene exposure can occur in occupational settings (chemical manufacturing, pest control) or through household use of products containing this chemical. High levels may cause symptoms including headache, dizziness, nausea, and liver or kidney damage with prolonged exposure. This test is valuable for occupational health monitoring, evaluating suspected poisoning cases, and assessing the effectiveness of exposure reduction measures.
