At a glance
Women's cancer screening blood tests measure tumor markers, proteins such as CA 125, CA 15-3, CA 27.29, CA 19-9, CEA, and alpha-fetoprotein, that are markers associated with certain cancers affecting women. These panels are designed for women who want a biomarker baseline, have a family history of cancer, or are tracking marker levels over time with their physician. Options range from a single-marker test to comprehensive panels covering up to 48 biomarkers.
Best suited for
- Women with a family history of cancer or known genetic risk factors who want a biomarker baseline to review with their physician
- Women whose doctor is following tumor marker levels over time, for example after a previously elevated result
- Those comparing a single-marker test, such as CA 125, with a broader multi-marker screening panel
- Health-conscious women who want supporting labs, CBC, LDH, amylase, and stool-based colorectal screening, alongside tumor markers

The importance of testing
Tumor markers are proteins and antigens that circulate in blood and can rise in certain cancers. CA 125 is a marker associated with ovarian cancer, CA 15-3 and CA 27.29 are used in breast cancer monitoring, CA 19-9 is associated with pancreatic and some digestive-tract cancers, CEA with colorectal and several other cancers, and alpha-fetoprotein (with the AFP-L3 fraction) with liver health. Measuring these markers gives you and your doctor concrete numbers to track rather than guesswork.
No tumor marker confirms cancer on its own. Elevated CA 125, for example, can also occur with endometriosis, uterine fibroids, or pelvic inflammation, and CEA and CA 19-9 can rise in noncancerous conditions. That is why these results work best as flags to review with your doctor, who can interpret them alongside imaging, physical exams, and your personal and family history.
The broader panels on this page pair tumor markers with supporting labs, a complete blood count with differential, lactate dehydrogenase (LDH), amylase, thyroglobulin antibodies, and a stool-based fecal immunochemical test, which add context on immune, pancreatic, thyroid, and digestive-tract health in the same draw.
A single result is a snapshot; the value compounds when you establish a baseline and watch trends over time. If you have a significant family history or known risk factors, discuss with your physician which panel breadth makes sense and how often retesting is appropriate.

What do women's cancer screening blood tests measure?
They measure tumor markers, proteins such as CA 125, CA 15-3, CA 27.29, CA 19-9, CEA, and alpha-fetoprotein (AFP), along with supporting labs like a complete blood count and LDH in the larger panels. Each marker is associated with particular cancer types, and levels are used to establish a baseline and track change over time with your doctor.
Can a blood test confirm cancer?
No, tumor marker blood tests are not intended to confirm cancer on their own. Markers can be elevated in noncancerous conditions (CA 125, for instance, can rise with endometriosis, fibroids, or pelvic inflammation), so physicians interpret results alongside imaging, exams, and your history. View any out-of-range value as a flag to review with your doctor, not a verdict.
What is the difference between the CA-1, CA-2, CA-3, and CA-4 panels?
They differ in breadth: CA-1 includes 5 tests covering 6 biomarkers, CA-2 includes 10 tests with 43 biomarkers, CA-3 includes 13 tests with 46 biomarkers, and CA-4, the most comprehensive, includes 15 tests with 48 biomarkers. The larger panels add supporting labs such as a CBC, LDH, and amylase alongside the core tumor markers. Your family history and risk profile, discussed with your physician, are the best guide to which breadth fits.
Can I order these cancer screening tests without a doctor's visit?
Yes, the panels and individual tests on the partner page are sold direct-to-consumer, so you can order online without scheduling a doctor's appointment first. You then complete a blood draw at a local patient service center and receive results electronically. Sharing those results with your own physician for interpretation is strongly recommended.
Is this testing available in every US state?
No, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. If you live elsewhere in the US, you can typically order online and test at a nearby patient service center.
What does the CA 125 test measure?
The CA 125 test measures cancer antigen 125, a marker associated with ovarian cancer that can also be elevated in noncancerous conditions such as endometriosis, uterine fibroids, and pelvic inflammation. It is commonly used to track levels over time and monitor change rather than as a standalone screening verdict, which is why results belong in a conversation with your doctor.
