## Quick answer Yes, TRICARE covers laboratory services when they are ordered by a doctor and are medically necessary to diagnose or treat a specific condition. Most diagnostic blood work, pathology, and urinalysis are fully covered ($0 out-of-pocket) for active duty service members and most beneficiaries using TRICARE Prime, provided you use an in-network laboratory.
Details
TRICARE generally covers a wide array of laboratory services, including blood tests, throat cultures, fasting blood sugar tests, and pathology. However, coverage depends on the **medical necessity** of the test and whether the laboratory is **TRICARE-authorized**.
### Coverage Rules by Plan (2026 Rates) * **TRICARE Prime (and Select for Active Duty Families):** Lab work is typically covered at a **$0 copayment** when performed by a provider in your regional network (Humana Military in the East or TriWest in the West). * **TRICARE Select (Retirees/Others):** You may be subject to a cost-share or deductible. For Group A retirees in 2026, the cost-share for office-based outpatient lab work typically aligns with the primary or specialty care visit fee, though standalone lab visits often have no separate copay if performed at a network facility. * **Point of Service (POS) Option:** If you are on a Prime plan and visit a non-network lab without a referral, you will likely face a 50% cost-share after meeting your POS deductible.
### Genetic Testing Genetic testing (such as screening for hereditary cancers or fetal chromosomal abnormalities) is subject to much stricter rules. TRICARE only covers genetic testing when the results will directly influence the medical management of a beneficiary who has symptoms of a genetic condition or is at high risk. **Note:** Non-invasive prenatal testing (NIPT) is covered for all pregnant beneficiaries as of recent policy updates.
### What is NOT Covered TRICARE will not pay for lab work that is: * Part of a non-covered procedure (e.g., blood work for elective cosmetic surgery). * Performed for "information only" or administrative purposes (e.g., tests required for a job application or sports camp). * Routine paternity testing. * Conducted at an unauthorized laboratory.
### Using the Right Lab To avoid unexpected bills, ensure your doctor sends your samples to a network laboratory. Major national chains like Quest Diagnostics and LabCorp are generally in-network, but you should verify your specific region’s provider directory via Humana Military (East) or TriWest (West).
## Who this affects * **Active Duty Service Members:** 100% coverage with no out-of-pocket costs for authorized labs. * **Active Duty Family Members:** No cost-share when using TRICARE Prime or Select with network providers. * **Retirees and their Families:** May have small cost-shares depending on the plan (Prime vs. Select) and laboratory type. * **National Guard and Reserve:** Covered under TRICARE Reserve Select (TRS) following the same rules as TRICARE Select. * **Survivors and Medically Retired:** Coverage mirrors the standard retiree or active duty family benefit depending on status.
